problem with UICP and 1gbov

[metalhedskater]

Okay so i just installed the dejontool UIPC and the 1g BOV....i had a problem...the service engine light went on so i decided to unplug the battery to reset it maybe....the light went off and then i noticed that the RPMS were a little weird....at idle they used to be at 1,000 RPM (before i installed everything)... now they are at 500 RPM....my question is: Is that normal? has anyone had this problem? what are your rpms during idle?

[ashah000]

Was your idle fine after you installed it, but before you reset it?

500 is a little low.. but my guess is that since you just reset it.. it might take a while for the ecu to smooth the idle out. Happens to me when i reset my ecu.

[metalhedskater]

yea i think it was fine before i reset it........but ill keep you guys updated...thanks for the helpful help!!

[ashah000]

It could take a while for it to smooth out. When I reset mine the idle is high.. and when I am slowing down the rpms stick at like 1700 and then when i come to a complete stop it will go back down to the normal idle.

look closely at the idle , you are probably at about 700 or so rpm, which is about normal. the reading lines are bunched up tighter that the rest of the gauge below 1000 rpm. [which i woul dthink of as a high RPM]

If you have your AC on your idle will be lower. Something to just check on to make sure you're not getting a weird reading.

The 1g BOV isnt vented is it? Have to ask...

Make sure the MAS is plugged back in. People often forget that, and it will give you a CEL. Cant think of anything else you might have had o mess with for a UICP job that would give a CEL.

if the MAS isnt plugged in, the car wont run it will start then kill. Give the ECU a day or 2 and it should be fine. mine did something similair after i reset my ECU when i installed a UICP and a 1g BOV.

I'd be willing to place a wager on that.

when i forgot to plug my MAS in, it ran incredibly SLOW.

someone else before had this sort of idle rpm problem too, i think in that case it was one of the screws on the throttlebody was too lose/tight. might wanna check that out too.

[BoostedSpyder]

i was going to mention the MAS, but thought better of it for the sake of MHS... lol

and my RPM increases when i turn on my AC, idle is like at 900 or so

The car will run with the MAS unplugged. I got a few miles from home more than once before the CEL reminded me to plug it in. Ran a little rough, but then again, my car always runs rough.

thanks guys! but still the rpms are the same....when i start it up after a few hours of driving like 8-12 hours....the rpms are like at 1,000 or 900...but once i start driving it, the rpms go down to 500 when i come to a stop and idle i.e. at a stop light... For sure i checked the MAS and it is connected. I did however tighten the stock tube that connects to the elbow adn throttle body pretty good. I also had to push the stock tube up a little on the elbow to fit the ucip in my engine bay....could that be a reason? Do you think perhaps i fucked up a few wires that connected to the MAS....it all looks fine to me. So i have no clue.

[metalhedskater]

also, by disconnecting the battery, does it also reset the ECU or do i have to manually do that from the ECU? ...because you know for the stock stereo, if you disconnect the battery, it asks you for a code....well mine didnt do that and i was pretty suprised.

[ashah000]

You probally did not disconnect it long enough. Mine asks for it when it has been out a while otherwise sometimes it won't ask if it has been out for a hour or so.
