i have a couple more avenues to try but i will still proably talk to ed about an ultimate as i want to know what there capabilities are.. mapping isnt an issue i know an ace mapper near me and i can get dyno time dirt cheap.. i want a decent ECU thats all.

DTA, Superb ECU's

[Gemma85]

ian im so jelous i love your lawn mower car lol

[squarepants]

have you managed to de-badge it yet?

[Ed]

Have you actually used DTA? So many people quote stuff on ECUs and have never even used one or know how too...

In any case blue emanage would do this K11. Spend big bucks to write nice things on a spec sheet if you want, but for fuel and ignition blue is all you need. If you want to go further sure, fit ultimate, get launch control/TTGS no limits on injectors etc and it will do tonnes more. I did another pulsar this weekend. On ultimate, the poor guy blew his 5th gear on the way home, too much power ?

BTW imo DTAs software is not that nice. I've used alot better. Experience does count. Hows this though. I mapped a GTIR with blue e-manage a while ago, it was 0.1 second slower (got an 11.7 1/4) than a higher tuned and totally stripped out GTIR with Motec mapped by norris designs. I know both owners well, as you can imagine the guy I mapped with the blue was very chuffed, and the one by norris was not quite so lol.

[k11stew]

sorry to hijack the thread, but seeing as were talking about it ill chip in.

ed, i will be in the same boat as mr raceworx soon, once the tomei cams and other bits are fitted. am i right in thinking to get the best out of the cams all that needs adjusting can be done on a blue emanage?

thanks for any help. stew.

[micra_pete]

the figures and times ed is producing with the e-manage say alot, i personally don't 100% trust piggy-back units, but bang for buck, if i couldn't work on my own ecu's i'd go e-manage ultimate and a good mapper (ed seems good, and tracable if any poor work was done) everytime.

ed - in regard to the norris thing, i got hold of a re-mapped 300zx "chip" from a well known uk tuner, you would not believe how little they had changed, and how little they obviously knew about nissan ecu's

[Ed]

pete, I can TOTALLY believe that, I have had to fix and re-map/config many e-manages from other so called "jap tuning specilists" its astounds me. When they dont even know how to set up the things and then try to correct the strange mapping results they are getting with using crazy correction on airflow maps etc makes me cringe/cry/stare in amazment. The price people have also paid for these bodges is even more amazing!

K11Stew, when you change cams you totally change the way the car breathes, its totally likely therefor that all the timing and fueling maps will need optimising to some extent. Basically you could end up with worse performance with cams than without if they are not mapped into to do the job.

[k11stew]

so would a blue emanage do this?

and what sort of prices are we looking at to set one up?

[Ed]

Blue e-manage I charge 150 to fit + £25 hr mapping. The extent of mods on the car affects how long this will take but your looking at 2 hrs for a normal tune up.

Ed

[k11stew]

bargain!

ill be in touch.

[Ian]

how do you map them ed? on the road in real time with a lappy?

[Ed]

yes, as much as i would like a r/r 1, its not portable and 2, its not real life.

[Raceworx]

im either going to use an apexi power FC with GTiR wiring loom modded to fit... as im going to use an SR20 TB and MAF or a HKS FCON PRO-V iv not wuite nailed the ecu down but iv got a parts list ready for the new CG13DET.

i would have gone e-manage if i wasnt going big turbo in the near future for now ill run with what iv got lol..

[micra_k11]

lukin sweet! what side skirts are those?

[Ed]

That E-manage ultimate I fitted last weekend was an upgrade - from power FC! the only thing the power FC can do that the e-mananage cant (Nissan specific) is increase the rev limit, in every other way it can do more.. I dont see what maf etc has goto do with it as the ultimate e-manage for example can run with anything, or infact you can remove the maf all together and run on a map sensor instead if you felt like it! size of turbo makes no difference.

I am only saying this since claiming not to use something that is perfectly suited for the job just because you want to run a large turbo (what one by the way?) is inaccurate and not true.

[Raceworx]

GT25R aiming for 200WHP not disclosing any more details than that yet.. if you can tell me that the ultimate will run with an SR20 TB and a suitable map sensor.. then the jobs yours once the engine is built and in as long as it less than 1.5K lol

[Ed]

GT25R is what I have on James K11. Superb turbos. Should spool up very fast on his and make a huge fat chunk of torque!

Ultimate would easily run with SR20 throttlebody, and you would need the greddy map sensor. FYI for me to supply the whole lot (EMU + Loom + MAP sensor) is £620 to have it fitted is £200 and to map is 25hr.

Blue e-manage would do the job as well, but may not cope with larger injectors as well - but thats a limitation of your stock ecu - NOT the blue e-manage, however it would require much less mapping than the EMU.

[Antony]

ed?....

erm...

would you be up for mapping my turbo setup?

Garrett T2, Daveys top mount cooler, emanage blue, and thats about it at the mo..

im gonna get an adjustable wastegate so i can run as little boost as possible untill i get injectors and a 2mm spacer...

can you let me know please?
thanks

[Ed]

No problem, cant do anything untill after JAE, but no problem.

[micra_pete]

the thing that makes me edgy about the e-manage is, as an example, the cg ecu code takes a reference from the maf for 13 seperate things, not all directly load related, but used for referencing and being used as a condition for many things, when you remove that reference things will either be accessed all the time, or not at all, or at the wrong time, that i dont like.

i appreciate thats how piggy-backs operate, and they work, but that would worry me a little.

the new self mapping options i felt were a good idea on piggyback units, as it enables the unit to maintain a value, because i wouldn't trust it as a set value, the reason for this is the nissan ecu doesn't always use one set value for - example - the fuel map, sometimes its not even used, so if your aiming for 15:1 with x amount of fuel setting on the piggy-back at a certain load at a certain rpm, that may not always be the correct amount.

however people still see good results, if you see good results who am i to argue

if you understood that, your doing well

but ed, i'll be honest, i don't use the e-manage, so don't know a huge amount about it, im not going to pretend i do

[Antony]

thanks ed...... we'll talk..... when i get it all fitted..lol

[Ed]

Pete, I agree, which is why the ultimate is so clever, It doesnt interfear with the signels going to the ecu. even if you change the maf you select what the correction is and the stock ecu sees what it would anyway, - the blue doesnt do this. The EMU doesnt even modify ecu signels when changing injectors, it intercepts the duration and then cuts or adds to this. Again that stock ecu has no idea this is happeneing. The emu also interfaces with the crank angle sensor so again in altering the timing it does this without altering anything the ecu sees. The EMU is almost standalone which is how its able to on some cars remove stock rev limit and do so much. It just uses the stock ecu for reference for everything it does.

[Raceworx]

thats sounds fair to me.. will it remove the stupisd 112mph speed limiter though?? as its just not quick enough with the power it will hit that in no time on the straights..

it wont be for a while though as im not spending as much cash ont his one as i did the SR20 well same amount of cash just not as fast lol

[Ed]

if it really has a limiter youll need a de-limiter unless you use the ultimate that can also de limit cars.

[Raceworx]

so the ultimate can de-limit thats fine then... trust me it has a limiter its sad knowing i can only hit 112mph

[micra_k11]

what side skirts are those?

[Type-R]

So with my blue emanage and cg13 ecu my cars limited to 112mph?

How do i unlimit this in the cheapest way possible?

[rlees85]

wel howcome ive done more then 112mph and i also know other people in micras who have done the same ? (on private roads, blah..)

[micra_pete]

your ecu has a speed limit? what year are you on?

i really need to hurry up with my nats ecu's......

[Raceworx]

Pete :- 2000 nats CG13DE...

Rich.. you have gone above 112MPH indicated speed on the speedo but trust me its not actually 112mph mine hits a limiter at 120MPH indicated* the red one did aswell that was a 1998 CG13DE.. about 4.5K RPM in 5th gear anyoone who says they have gone mroe than that in a facelift micra id take that with a pinch of salt.. both of mine have had this limiter.

sunny i think those speed cut limiter devices would work but i dont know.. if needed oill get a video of it next time im at bruntingthorpe.

[micra_pete]

right then, i'll check that out as im working on the ecu.

[tommo]

my speedo says 117 when it limits. strange....

[rlees85]

my bad, i thought you meant 112 indicated!

[Type-R]

LOL my speedo says 100, when i went brands hatch, i have maxed out if fifth gear dnt no how fast it was speedo needle went off the clock. Hence i want to get the 1.6 gearbox on my car now. But whats the point if it has a limiter.

[Raceworx]

well iv got my engine to work on its a 1.3 auto the one Rlees baught but didnt need.. was a journy and a half getting there with richmicratwist in tow... we nearly crashed when rich decided to sing sheffield wednesday songs as loud as possible down the intercom whilst i was trying to drink some fanta..deffand and chocking with tears streaming from my eyes trying to controll a car isnt funny :P

many thanks to Rlees hope the neighbours didnt complain to much

[Swiper]

can i ask you where you got your sr20 head gas flowed and ported and how much it cost, unless you did it yourself. thinkin of doing it to my cg head as it's off the engine.

[Raceworx]

i did it myself dude took me about 12 hours in total!! im going to do it t the CG head when i get it off.

[rlees85]

i did it myself dude took me about 12 hours in total!! im going to do it t the CG head when i get it off.

just out of intrest: how? did you need any special tools?

[sonic]

I'm not sure if mine has a limiter, '92 1.3 March, I've pushed it to an indicated 115 (private proving ground) but running 185/60x14 front tyres, (wouldn't that make the speedo under read ?) and didn't feel any sort of limiter cut in at all.

[rlees85]

if thats in 5th you'd be ages away from the limiter
on my 1.0 its

1st 30
2nd 58
3rd 82
4th 109
5th 130 ish i think :S (obviously never hit that one)

(top speed limit: 120 mph tho i never hit that limit either)

[sonic]

Cheers Rich, I'll give it a thrash in the lower gears to see if it cuts in on the way to work later.

[rlees85]

yeah the way i found out if i had a limiter before i had my rev counter was: put it in first, take a keep breath, and planted it n when u hit the limiter in 1st it really throws u back :S

[Ian]

going to the limiter is pointless on standard cams. Your march will have a limiter though. The rev limit is something different to the speed limit raceworx is on about.

As long as the europe and jap ECU's are similar, you wouldn't have hit a limiter on the proving ground in the march because its pre-facelift.

[Raceworx]

pre facelift micras dont have a top speed limiter they could pull to a theoretical 145mph top speed at the standard rev limit in 5th gear with the right power.. my car is a facelift and has a top speed limiter of 112mph as nearly all small jap/import cars do.

Rlees i only did a quick port clean up and gasget match i used a grinding kit and a flap wheel of varying degrees to polish the exhuast glass smooth.. it was time consuming and went through shed loads of grinding bits..

[Raceworx]

right a glimps into the raceworx engine shop (my nans) iv got hold of a CG13DE auto which is going to form the base of my CG13DET project.. as you can see i stil have the SR20 which is going to give me afew bits anyway to the pics :-




it looks like its not had an oil change for a fair bit but theres no wear on the cam lobes which is good




Nope its not a super light fly its proof its an auto with its starter gear :-


I took the inlet off but rememberd i had made a cutdown inlet for experimenting with a while ago!! :-


then glancing at the SR20 nkowing i wanted to use its throttle bodie i had a brain wave lol :-



i can use this top section as my inlet plenum all i need is some ram pipes welding to the cut down inlet a nice flat plate that bolts up and we have a side draught SR20 Thrttlebodied inlet



got it ready to take the head off but the batteries ran out!!

[tommo]

good progress man!

se you in the mornin lol

[Gemma85]

nice 1 ian your nan is so cool lol

rotorstock 3 video you can see my car in the background lol :P was a god show roll on next years

[Swiper]

you can see my car in the background lol

i was expecting a very distant 'blink and you miss it' kind of thing. quite a good close up really. the show looked awsome. will you be going to the japshow finale at the pod?

[Raceworx]

duno dude.. quite possible
