What should it be set to? Right now it's at 0.4 (assuming I'm looking at the correct one). UKspec's bin has it set to 0 which people seem to be having good results with. Anyone else care to share there setting?

it should be set to .2 above your idle TPS value.

It is there to keep the MAP enrichment from triggering at idle. If your idle starts to stumble a little, the MAP enrichment will make it worse.

Also, double and triple check the wiring connections. Then unplug and re-plug the connectors at the Maft Pro. The tiniest bit of noise on the MAP signal can mess your idle up.

Well I had a chance to mess with it last night and set it to around .8 after seeing some other people have it set to that. It didn't work at first but after a while it did idle fine. Even reving it up didn't cause the idle to fluctuate. I didn't get a chance to test it on the street since the roads were wet but my fingers are crossed that was the issue.

As for the wiring it's been checked multiple times so I doubt that's the issue...who knows though with the recent wideband install something might have been jogged loose.

Well I guess I spoke too soon since it seems to be worse than before. I've tried all sorts of settings from .6 all the way to over 1 and it was actually worse than before. The wiring seems fine and the only thing I can do at this point is re-wire the whole thing and if I'm going to do that I'm just going with something more proven.

Any other ideas Bob?

Terry

[TurboBob]

set that limit like I said, and take another log.

Send or post the log and BIN.

I want to see what data is fluctuating.

where is your MAP sensor plumbed to?

Bob

[Maximal]

Here you go Bob...

Maf is plumbed into a T between the intake plenum and FPR.

Terry

[TurboBob]

just wondering: are your o2 sensor(s) uplugged right now?

I just want to know what the ECU is doing right now, can you check the trims and malfunction codes?

B

[Maximal]

Yep...stock o2 sensor is unplugged. I can't get the trims since I don't have a logger that works with the overclocked ECU from you.

Terry

[TurboBob]

perhaps un-overclocking might be wise so we can troubleshoot the wierdness.

The stock parts are inside your ECU's case.

B

[Maximal]

I've got a stock ECU I can throw in it. Been meaning to try it but was hoping that I was just missing a setting or something.
