UBERDATA HELP (SOLVED)
 

ok i just got my ecu back from projekteg. I put it in and when i start the car it jumps to 2000 Rpm and will stay there for about 3-5 seconds. Then it will drop under 1 and then die. So i stuck my missing link back in and it ran better the idle was a little above one til it became warm. The thing is i shouldnt have to run the missing link witha chipped ecu. Why does it run better with the missing link in? PLease help

IACV problems...?

Although, still very weird. Missing link should have no affect on anything in the vacuum ranges.

Did you search on the Uberdata forums at all for any similar symptoms???

curious as to how much vacuum you are pulling at idle. With both the missing link on and off?

just sitting here thinking. didn't you have an afc hooked up? did you unhook it? if so, how? did you unwire it from your harness and put your harness wires back to stock? or did you just unplug the afc from the subharness? or, is it still hooked up and your settings aren't set back to 0?

well i had some problems getting to school. I had to bring it home and park it. The car would not accelerate at all. something is messed up. In the morning it started and idled fine then when it warmed up it started jumping from about 1 to above 2 rpms and running like ----. i couldnt drive it. My brother came home on lunch to look at it and there are no check engine lights and the iacv or w/e was testing out to be good. vacuum with the car started with the missing link was like 16-18 i believe if i read it right. We are going to try to fix it when he gets off work. Could the ecu be screwed?

ill check all that when i dont have the missing link in the car dies in like 10 sec if that afc is out and wiring to injectors ill look at. i read some stuff on the uber forum that said clean the iacv and things like that so i will try that also thanks for your help

The IAC wont make it die, just high idle if it goes bad. Is this tuned? How do you know its getting enough/too much fuel? Maybe try reburning the chip. Have you looked at the spark plugs?
