Idle issues
The engines idle only runs at 1500-1700rpm, if i try to lower it then it will go up and down and later die.
When i drive the car on the road it´s working wery well.

Yes I have try to using 2-wire Bosch idlecontrol but now i have disconnect it.
And i have the VE and spark at the same value but when the engine comes below 1500rpm it dies

I have connect fuel pressure regulator to the system so i have lower fuel pressure at idle. Befor I have 1,5 PW and now 2,5PW but it is same with the idle.

You should know that on a warm engine ,having to rich ve-bins at idle the idle will be high, and on ethanol the effect of over enrichment is not as evident as if you run on gasoline.
So the engine might run very well at idle but you can´t get the rpm:s down.
The answer is in "moonshining" (hemmabrännare på jänkespråk) smell in the exhaust

I see that you are running 1.0 ms delay and 50 % pwm. You might try increasing those a bit. Too low will cause idle problems.
Turbo motors I've squirted. 4cyl subarus, 6 cyl subaru with vvt&vvl, honda3.5 with vtec, aircooled vw's, toyota v8, 2.5l autocraft, turbo intercooled yamaha rhino, more to follow

But I run low impedance injectors?subie4me wrote:I see that you are running 1.0 ms delay and 50 % pwm. You might try increasing those a bit. Too low will cause idle problems.
I have read the manual:
If you have low impedance injectors (less than 4 Ohms), set the:
PWM Time Threshold to 1.0 msec, and
PWM Current Limit to 75%(30% if you have installed the 'Flyback Board' daughter card).
If I lower the PWM more than 50% the engine stops, how hight can I go up?

But should I have 75% or 30% PWM I have MS1 V3.0 card
Do you have idea what I should do??

If the delay or the pwm is too low , it will cause an erratic idle , but it will run better at higher pw's. I have seen this happen. If you have a v3 board, then you should be able to run the pwm very low. Try increasing the delay a bit. You won't hurt anything at idle.scirocco_per wrote:Lance

Idle issues
Have you tried to get your car running on gasoline? This might make troubleshooting easier.
Then I believe you can just scale the VE after that for the difference in AFR. You will need to search the threads that have E85 in the subject to find out exactly. I hope it wasn't more than 6 month ago. But, at one time there was alot of dicussion about using E85 and how to switch from one to the other. There was even discusion of how to implement the sensor GM uses to adjust for different ratio's of gas to alcohol.
