Yeah, it was tuned for the 30# injectors, although I didn't get it all ironed out great last summer  before I put it away for the winter and this happened.

According to the ALDL output it seems that the IAC is at a reasonable number of steps, TPS appears to be reading correctly. The Coolant Temp Sensor and MAT sensor also appear to be reporting reasonable numbers. Hopefully I'll get some time this weekend to do more diagnosis.

Thanks,

Thanks for the reply GPChief.

I probably should have added more back story, my car is far from stock and a bit of a mutt. I had 30# Ford Red tops in there prior. It ran alright on those, but I'm having a lot of trouble since I switched to the L67 injectors.

I can modify the BPC constant so that it starts at a reasonable AFR, but after a few seconds of running, it goes super rich. If I lean out the BPC, the INT goes through the roof when I first start it and it still goes super rich. To me that makes me think it isn't 100% injector related. I may switch back to the 30#r's just to be sure, but it seems like it goes super rich after 5 seconds of running no matter what I do.

As a side note, my battery died after the car sat unused a while. Is it possible that a weak battery could be part of the problem?

I'm trying to troubleshoot a few things right now. Back story:

Last fall there was a slight knocking sound. I had a few spare injectors, tried swapping them with no luck.

Left the car alone for the winter. This spring I installed some L67 injectors, and the intermittent knocking sound is still there, now i'm relatively sure it's a lifter at this point but haven't torn into the motor yet.

A new issue arose. Now, no matter how much I change BPC the car starts, idles ok and then goes rich as hell, to the point that there's unburnt fuel vapor coming out of the tailpipe.

I tried a bunch of things in $8F and bailed on it. I decided to go code $59. I've been having a bunch of hassles in $8F historically and got tired of it, figured I'd start fresh with code $59. I have the same issue with code 59. I adjust BPC vs EGR and it starts great, decent AFR then goes off the chart rich...

Car has good vacuum at idle, coolant and MAT and MAP sensors all working appropriately, and no CEL

Does anyone have any ideas?

I'll take the headlights. Please PM the total Shipped to 44060.

In the effort to turn my damn shift light off, I've found that my XDF seems to be crap when it comes to the Shift Light constants. I can set COOLANT THRESHOLD FOR E-LITE ENABLE to 151C and it's still on! I've corrected the XDF so that the correct N/V ratios are under the proper headings, but nothing seems to be working. Can anyone provide a working XDF? I've used $8F v1.2 $8F without much luck, I was told a while ago that $8F v2 wasn't great. Any help is appreciated.

Thanks,

Jon

Pretty much what the title says. I have the pipe from turbo to intercooler with a DSM style blow off valve flange welded to it. Welds don't look the best, but they don't leak. I ran this for about 2 years, now I'm completely changing my turbo setup so it's for sale.




$40 plus shipping.

Good luck shoehorning everything in. I'm having a hell of a time getting my GT3271 in even after relocating the battery. Of course I'm not running a FMIC yet, and the stock SMIC is really in a bad spot combined with the 3400 tb location vs the old 2.8/3.1.

Very interested in seeing pictures of the project.

Is that an ebay turbo?

No bin here, but maybe I can help with your trouble.

What chip are you using? Does it require an offset, jumper moving etc?

You sig says you have a 3 bar map, how have you modified your bin accept this?

Have you burned a working bin to this chip previously?

What do you mean by you have no idle. Does that mean it starts and idles poorly, or will not start and idle at all.

What map sensor are you using? Any error codes?

Have you checked for vacuum leaks?

CROSSOVER SOLD!

I also have a set of TGP manifolds that have been ported to match 3400 manifolds for sale: $75 + shipping.
