I will. I usually bring my tuning rig to these meets in case someone wants a free Stage 1/2 open source map flash (your free maps or mine).

If you are throwing codes that is probably not it at all. Even without adjusting latency, on 750's, 650's, etc I never would see a code thrown (but fuel trims would be at +20-25%). Heck, my front O2 works fine. I even re-soldered that ripped wire and it is fine. Anyway, if you need to borrow my WBO2, let me know.

You have seen what it was doing a few months ago when you were riding in my car. It is throwing codes. I will be doing a WOT run and it will be running 11.8 then just spike to 20.44 and then sit there, it will also just sit there idling at 14.7 and then spike to 20.44. I need to run through the diagnosis steps in the shop manual to see where the problem is, if I can even trace it. I am thinking of throwing the stock fuel pump back in and see if the fuel pump is the issue.

Yeah but the WBO2 was showing good numbers, dead on fueling at WOT. Plus if you were doing WOT runs and you ever spike to 20.44 in reality, the car would fall on its face and crack the ringlands. I don't think it is the FP, but it doesn't hurt to hook up a fuel pressure gauge. If you throw the stock FP back in make sure to change your scaler back and latency. Also, look at the fuel filter if you remove the pump. It may be dirty. Have you tried using a voltmeter (circuit tester function) on the front O2 harness to see if the ground wire has continuity?

Will do. You want a BCS kit as well? You gotta get a tune for it though, but if you are running open source its all of 2 minutes to change the WGDC numbers down about 15%.

***gabedude*** · 07-18-2008, 04:49 AM

Of several BCS's that I have tuned, no one really matches up to another. You do not want to mess with boost unless you can do several pulls and dial in correct WGDC settings and TD settings. It's not just plug it in and go. Now, if you already have a map that supports that BCS and turbocharger (running the same boost curve), the WGDC and TD settings could be kept the same. A 10% reduction in WGDC on a 20G is very different than a 10% reduction on a VF39 and since the tables are in WGDC%, this is important to remember. You can tune boost without a WBO2 though as long as you keep your current boost targets. But yes, it doesn't take long, however it will take a few WOT pulls.

***sti_kris*** · 07-18-2008, 05:02 AM

yeah i'll take the kit too. i'm not open sourced but i'll be getting a tune soon so i'll wait till them to do it all.

***sti_kris*** · 07-18-2008, 05:02 AM

Well, you know what I meant Gabe, didnt have to get all technical about it. It took me 3 pulls to get mine dialed in after swapping it.

It kinda sounded like you said, just remove 15% and flash it. Just clearing up confusion. Didn't I tune your BCS when you installed it or did you have it there? That week I had 4 tunes after work and most of them had a different BCS than stock, I just don't remember.

**FlyingPerformance** · 07-18-2008, 05:21 AM

no, I tuned my BCS. I think my final numbers were close to 15% off of what you had already had set up for WGDC. I didnt mess with my TD numbers at all though. He is running an AP though so no way to tune quickly anyway.
