Datalogged a quick 1-3 pass

Yellow4g63 · 06-09-2006, 12:19 AM

Done with a Zextronic wideband. If you want to view the log download the zxtronice program, http://www.zeitronix.com/images/ZDL_...ationFiles.zip

here is the datalog. http://www.3rdgearvtec.net/Andys%20V...ear%20pass.zto I not sure why the TPS was only reading 82% on the zextronic but I'll check that out when it gets a little darker. But my problem is the A/F at WOT. low 12's blows. My friend modded the injector correction for me and I'm waiting on right maf input since I'm running a RB20 maf.

Can you post your rom?

Yellow4g63 · 06-09-2006, 06:56 PM

I took a snap shot of it in a few post ago asking about which cells to edit. It looks just like your rom in everyway. The car just runs rich at WOT then good while driving normal.

My friend modded the orginal rom I got from you. Then I moded that 1 calld it test1. The one that I dataloged a/f was the moddedlagtime bin. The a/f was a little better than the rom I got from you. It didn't run as rich like on the dyno where it was hitting high10's low 11's. This new 1 test1 got the a/f to 13.0-12.7. I'll upload the log. My setup is Ve injectors, RB20DET maf.

I'm going to test out test2.bin tomorrow and see if I can keep the A/F nice and even. any sujuestions would be helpful since this is the 1st time I'm try to tune with out blowing my motor up lol.

Your AF's are going to bounce around at WOT, theres no way to avoid it. We were out testing my buddy's GT2871R set up a few days ago and his WOT AF's varied from 11.6 to 11.9. Thats on one of Enthalpy's tunes. His maps are rediculously linear. As in one third of the entire fuel map will contain just ONE value.

I think where you might be having some issues is the large AF change from the last two columns (which are leaner) to the ones right before it which are really rich.

I hate not having maptrace lol. I'm just messing with the last 2 because I was told thats where it hits at wot. any guesses as to where it bounces from while driving?

Try that one. The original rom I gave you was set for a RB25 maf, not the RB20. My bad.

I'm not sure how much of a difference that will make, they have pretty close VQ curves, but definatley a bone head move on my part.

I need to write a new version of CalumSult, I have an inkling of how to do map-tracing through consult, just haven't had the time.

Yellow4g63 · 06-11-2006, 01:21 AM

Well the S1 RB25 mafs are the same as the RB20's. Ahh man that would save me alot of time lol. I mucked with the fuel map and got my a/f in the 12.9-13.2 now. all is gude. I just need a lil tweeking for the 5500 range that went to 13.6 but fell off. I'll post the logs after I eat lol.

Yellow4g63 · 06-11-2006, 03:41 AM

Isn't that a little lean for a Turbo?

Yellow4g63 · 06-11-2006, 05:19 PM

I'm not turbo, I'm N/A. N/A SR20VE.

The little tweaking paid off went back to the dyno

Wish I could get some more timming in there but It started to ping a little at 4k to4800 before the VVL kicked in. Now I just need a header and a matching High flow cat.
