she looks healthy now!

had to be the gas. This is the 91 Stage 1 tune with the BPB modifications listed in this thread and 93 octane Hess fuel. Last two tanks were Shell and Valero. I'll do a few more logs on this tank (maybe some 93 tunes as well now that I have some real fuel) and post up.

Yes gass/petrol is a big variable everywhere and shiv carnt cater for all the different charataristics all round USA/Canada let alone round the world.

Gass is what I use for the Barbeque

ran the 93 map and still healthy no knock. Damn "petrol"

Nice! glad you figured it out

I flashed to the 91 tune and got just as much knock as with the 93 so I think bad gas might be my issue also. I flashed back to the stock tune last night and the ecu was still pulling a degree of timing over 5500. Topped off with half a tank of sunoco 93 and on the way to work this morning I could not get any knock so I'm going to try the 91 tune again later today and see what happens.

@Shiv@Openflash
When you say you've "never had much luck with E85 and BPB", what does that mean exactly? As in you had trouble working out the tune? Or it just didn't make more power? It just wasn't worth it?
Will it cause damage to run E85 and BPB together?

[lucid215]

he didnt make anymor power running the bpb and e85. only thing he was able to do is shift the power to the left a bit. so pretty much more power in the lower rpms but not more power over all

[Silver Ignition]

So I went and filled up on E85, flashed the Stage 2 EL E85 map and it DEFINITELY pulls harder than 93.
Ran it with the live graph view, no knock and not leaning out so she seems healthy too. Fuel trims bounce between -5% and +5% but LTFT sticks around 0%.

Dont worry about stft it will vary depending on lots of factors if LTFT is below 10% on an oft e85 tune throughout rev range then thats fine.

chgeck your afr follows the ol fuel table under load, check for knock which you have seems fine see logging thread below

AFR performs normal, although I noted it only drops to about 13.0 under WOT high load rather than the 12ish I'm used to seeing. Anything to worry about?

do a log
Open up tune in romraider and check that hte afr is following whats in the OL FUEL table for the rpm vs loadand that the ltft is less than 10 preferable less than 6%

LTFT bounces between -5 and +5 usually around 2.xx at any given moment I glance at it...I'll do a log

Perhaps you guys can shine some insight as to what I can't figure out, my car has a few mods (uel header, cat back, aem intake (it comes with a "tuned" maf plug in) and the power blocks), I also had the oft tune, not the latest one.

I installed everything but the blocks, car drove fine and logs were fine, seemingly. I don't know much about it. Once I installed the bpb I installed the bpb tune, car was running fine but after the first attempt it gave me a CEL P0171. I cleared it, checked that everything was nice and tight again, took it for another drive and it didn't light anything up. However, if I plug in my oft after driving for quite a few miles and check the error codes, it asks me to clear P0171, despite not having a CEL.

I figured I'd flash it back to stock, drove about 15-30 miles and that is my log, also just got a CEL a few minutes after that log with P0420, which I think may be due to my headers and was previously disabled with the tune. I wanted to see if there was anything I should address before tuning it to the 2.0 with the bpb adjustments.

I never logged the ltft before my power blocks because I never had a CEL to alert me, ignorant on my part but now I learned. What does this log tell you?

http://www.datazap.me/u/mauricio878/...e?log=0&data=1'

PS when I got my CEL my intake was plugged directly into the MAF sensor not the "tuned" MAF sensor that it brings, on the log however it is plugged into the "tuned" MAF sensor.

Fuel trims are terrible +/- 15 percent.
you either have leak in intake or gasket at maf sensor or at BPB or that "tuned" MAF thingo is upsetting things.


If no leaks found try Removing AEM intake put stock intake and stock MAF sensor back with OFT tune and all should be ok.

you will get P0420 on stock tune with catless headers that notmal.

Thank you, I had a suspicion but wanted to make sure. I'll let you know what I end up coming up with this weekend. I ran the car without the "tuned" MAF thing and they stayed up there so I'll probably check the gaskets out before going further.
