i am running 8*180cc injectors, i couldnt get hold of larger units.i read in the manual that if you run them in alternating mode then you can have them overlap when they when you go high up the map.
the problem is...the car will only run in 1 configuration
4 squirts per cycle and simultaneous staging
it wont run on 2 squirts nor 1 squirt per cycle
its a 4 cylinder and i thought i could run it on 1 squirt per cycle

alright 132

y cant u get bigger injectors r they hard 2 come by in egipt

steve aka stv firestarter

exactly....
i got it to work though...i had to change the ve table straight away to be able to catch it before it dies
the problem now ....is that it idles at.....
100% ve
i was complainig about 70....now what???

wot did u do can u tell me i c how i get on

as soon as i changed the staging to alternating....it started to stumble and i had to catch it with the throttle until i increased the ve numbers.it idles even better than it was with 4 squirts but the value is too high
i will try with 1 squirt tomorrow and see how it goes

What is the injector opening time set to in the constants page? It should be set to 1 mS.

yes it is....

fiat132,
The following may be useful on the opening times:

I have had some trouble with this myself - 4 squirts alternating worked best for me, but I am running a stock engine with stock injectors / harness. I have used a scope to calibrate opening / closing times, but it was hard to see what was going on. I will try the method in the link above next time I have a chance to play with the car.

i tried and while i was trying i remmebered that the manual said that the minimum with alternating was 2 squirts...
i will leave it at that...i willl have to see what kind of table which has an idle ve of 104%

Whats your ReqFuel?
