Today i got round to setting the base idle on my bt escort cosworth because it hasnt been right since i got it.

Heres what i did

1. Set the tps to 0.35v
2. My car has a L8 ecu so i did 5 turns anticlock wise to zero it and the 1.5 turns clock wise.
3. Let the car warm up so it would run without the iscv connected and then i adjusted it to 900rpm,then even with the iscv reconnected it stayed at 900rpm.

Great i thought ive sorted it,then i turned it off and left it for 30 mins to have a and on re starting it it roared in to life and revved to 3000rpm and stuck there!

I know i need to take it to a pro but id like to get it near enough myself.

Any ideas

Spec is grey injectors/gt28/twin pumps/L8 scs mapped
