At 3800, 1.0 works for 90% of people, being the ones with Tomei's, clones, etc.

We have local tuners here who run much leaner and still have that spike, even in FOURTH GEAR on a $1000 custom dyno tune.
I never understood why until I developed the load limits on my car.

I would not have even looked into the load limits if it weren't for your thread. Kodename47 was already playing with that right away. I just left it alone as to not over complicate things.

It's because brzedit and ecutek got those defs pretty early on, the rest of us were in the dark. Shiv had the defs for a few C roms, and none for the rest, so not everyone had the same issues there. I didn't know until I saw KN post about them and I compared 98 and E85 logs and saw they were both equally shit in that area on some cars and better on others and put 2 and 2 together.

I'll have to try the load limits you posted. I still haven't done that as I haven't touched the tune since May I'm still using the OTS Stage 2 load limits, which is why I said I was nowhere near the limits. I think I need to use yours to lean out the surrounding areas a little bit, then make my MAF curve "flat" there with no dip. I'm just VERY against flashing unless I have to, I can't get rid of the throttle dead spot without driving for a couple of weeks and I'm really sensitive to that.

Ah, you are right. I was going to purchase brzedit for that purpose and for the ability to log more channels.

Just got my OFT and had done the stage1 flash. Then after doing a little reading, adjusted my tune for the Crawford BPBs using this thread as reference:

After doing more reading on the ECU logging functions from @steve99 's excellent post : http://www.ft86club.com/forums/showthread.php?p=1842501

I noticed I was getting FBKC and IAM readings that his post indicated were not great.

I reverted back to the stock rom and took a 20 minute drive or so. After this I'm still seeing FBKC and IAM changes where they look like they're not supposed to be happening. Wanted to post the log here and see if anyone might have any recommendations. I'm running Shell 93oct on the last three tanks or so.

Use the unmodified stg1. Not stock.

latest datalog with UEL load limits, custom OL maf scaling, port injection ratios and Wayno's Base Timing B.

It isn't perfect, but it's starting to look better. Still a little lean in some spots, which concerns me a bit on this lovely 91 octane.

Only 3.44V is lean. Multiply 3.44 by 1.005 and 3.2 by 0.99.
You might be able to use 0.9 @ 3600 instead of 1.0 @ 3800.

And people stop posting graphs with every channel displayed that we have to go through one by one and turn off! Just post a graph with rpm displayed.

Thank you very much, making those changes now.

Sorry about the channels. Speaking of other channels, should I be concerned with those lapses of high ST fuel trim? (up to 17% at super light throttle). On the other hand...during WOT my fuel trims at 0 =

p.s. Where can I donate to make all of your help worthwhile? You're the man.

Which headers do you have?

Thanks. Let me try that. I made the change to Engine Load Limiter B & C tables and went back to the base MAF value at 3.2v. Will log it and see.

I have the open flash header.

[Wayno]

You're asking the wrong person about fuel trims. I've never touched my closed loop maf scale, so STFT is useless to me. I only care about repeatable LTFT in OL.

If you test and prove you don't have a leak, then scale closed loop and move on.

Got m,y Maximal Performance oil cooler installed... I think a block off plate for winter is a good idea, based on the temps I saw in ~34 degree F. Took quite a while to get warm, and it never really got hot.

http://datazap.me/u/docwalt/10-19-15...ta=1-2-6-11-12

Even in the afternoon at about 50-55 degrees F it took a decent amount of time to heat up.

http://datazap.me/u/docwalt/10-19-15...ta=1-2-6-11-12

Unfortunately I don't have a before and after, so I have no idea how long it would have taken to warm up as stock.

[Wayno]

It's supposed to be thermostatically controlled at 185. Yours never reaches 185 so it looks like the included thermostat is garbage.
