As the title says, my car won't run on 1.7, i don't know why, but i have it running fine on 1.6 aside from the pulsing idle.

I posted on the Uberdata site, but i don't think anyone even goes there anymore.

 

version 1.70 has IACV control.......i dont know if it actually works but its there........

 

I know, and like i said, my car won't run on 1.7.

 

why not? what does it do?

i had no trouble with any version from 1.2 up to 1.9.....

 

It fires and instantly dies.

 

thats odd.......there must be some setting your missing. maybe cold crank enrichment or something like that.

anyway you can maybe add the IACV control from version 1.70 to 1.66 but im not sure if it will work.

you need to post/ask on pgmfi.org and hope someone still visits the uberdata forum to help you.

 

I tried that, it didn't transfer over right, but i don't know what i'm doing with programming. I used to get a CEL with 1.7, that went away, but it still doesn't run...

 

there is a place called pgmfi.org for this lol

 

I'd suggest trying to copy the idle section from a base 1.70 map and use that on your imported 1.66 map. Sometimes with uber, you have to start from the begining and work ahead one step at a time. Anoying, yes, but its not like you paid for stability

Theres a bunch of settings in 1.70 (don't use 1.7, aka 1.7beta) that can really mess things up if you set them wrong. A base 1.70 gsr map (imported/altered to whatever ecu you need) should always start a car, with the worst-case being a rich 10:1 or lean 17:1 idle. It will start with both, but lean wont like it at all. 16:1 usually idles fine.
