Super S poor running

[CMF_demonical]

When i push it at wot 1 and 2 are fine but in 3rd there some kind of kangarooing it stall's then shoots up and again.
The engine is a 1.3 CG13DE with slightly ported head , CG10 pistons with brand new piston rings , stock exhaust maniford de-cated + 50 mm pipe and backbox , GA16 black injectors ,the stock airbox and a brand new lambda sensor. When i unplugg the lambda it seems to run better , that's why i bought a new one butt nothing changed.The MAF is working 100 % it got off a perfectly running micra

disconnecting the speed sensor wire at the back of the clocks should cure that demonical (shown about 1/3 of the way down here)

Will try that tommorow frank and report back

You the maan Frank thank you problem solved

 

[CMF_frank2]

the only problem is that the ecu will probably drop out of closed loop when you are cruising and have to add a bit of throttle when you come to a hill, and you will probably get acceleration enrichment all the way up the hill (and use more fuel)
it will probably depend on what injectors you run, i get on a lot better with the later topfeed ones personally
an option would be to fit a switch @ wot only, or just a bypass switch

Im running it on LPG on trips petrol's just for races it's at a high price here

Here's a clip of the acceleration it goes uphill after 120 km/h

thats pretty f/kin loud lol
is the lpg injected ? (4 nozzles)

 

[CMF_demonical]

No it's a single nozzle entering just under the MAF sensor , the video is on petrol

mine was the basic single jobby too, a GA16 t/b gave good gains on gas on mine because of that fat nozzle blocking the stock t/b
