Hi guys ..

Just started to tune 2150s + Omni 4 bar on pump gas . They dont fire on 96534706 with out pressing the paddle . Running open loop. at idle. I tried different latencies and scalings but they wont fire on the key. Min ipw used - 1.072 , 1.104 , 1.112 .

Any one faced the same scenario ?

2150 and SD people

 

What is your throttle position reading on evo scan?

 

Hi 4b.

It reads 13.3 %

 

Sounds right, i know if its above 16 it causes your complaint.

 

I did min ipw patch bro. I have tried these 3 ipw values . 1.072 , 1.104 , 1.112 on 965347
Its quite odd that 1.104 works well on 90556701 + JB latencies.

Switched to 9653 and it never idled. What are your MAP VE values in idle areas ?

 

74 or so

 

Lower your Cranking IPW from 7 to 82 down... from 50-82 I would have it at .5ms

 

Thanks for the reply freddie.

Lower them using formula -- stock value [ old scaling / new scaling ] ...

Do i need to lower the VE values in Idle areas as well ?

Scaling and ipw have inverse relationship ?

 

I just lower them until **** works...

 

Update -

In case if some one is going through this problem [ pump gas ].
John Bradley's Latencies are spot on.

Lowering Cranking IPW helped.
Increasing MAF comp vs coolant values in lower temps.
Adjusted the BISS.

Car fires up right away on key with out pressing the throttle.

Thanks everyone for the help.
