@troek Well spotted mate, missed that one :-)

Thats is weird it should be like +20 or so something is off @clintavo check your timing tables in your tune. did you do any editing ??

Depends on the situation Could just be on a cold start...

If it's bogging, it could be a few things. AFR or ignition timing, so base timing or transient. Or it could be that FBKC is causing a timing drop enough to be noticeable.

IMO just don't boot it from that low RPM. The engine is knock prone at low RPM high load anyway. I really think flooring it below 2.5k is a bit pointless. You never need to floor it that low apart from in 1st and maybe 2nd and then you won't have the issue anyway as you'll fly through the range.

I too have the bogging problem. I was pulling out of a gas station across two lanes when I noticed a car approaching quicker than I thought. "No problem I thought, I'll just apply more throttle and avoid being in the way." The car basically stopped and bucked across the road, and I was lucky I wasn't t boned.

Have a look at a srock D00C rom and a modded D00C see if any of the drive by wire throttle tables have been altered, might be another cause of that type of thing

stock roms in tactrix thread below.

yeah, i didnt think about that, makes sense too as his rpm is 1300 ish.

i just uploaded the stage 2 uel e85 rom. right off the back i can tell its better. the throttle response is a lot more accurate then the 93 rom. i know its still learning but from what i saw while under throttle my stft is around 3-6% and ltft is at 0%. off throttle stft is 0% and ltft is about 14%. i just barely put 9 miles on the car so i know theres a lot of learning for it. cant wait to go wot haha

Running OFT 2.02 91 stage 1, and having a heck of a time trying to get IAM up. Running California 91 gas from Costco - not sure if this is the issue? Anyways, if someone can take a look below, I'd appreciate it.

It was a cold start. I have not modded anything in the tune.

Admittedly, flooring it a such a low rpm is rare, but kind of like d1ck said, I was about to get backed into. Flooring it resulted in zero acceleration, and REALLY got my attention.

I'll make a log of the bog.

You live in Foothill Ranch?! So do I I think I've seen you driving before! I'm on the 2.01 maps and I only run Chevron or Shell. I've done 5 datalogs and have driven pretty hard on all of them and haven't got the IAM to drop below .78. I think you should run that Costco gas empty and try Chevron or Shell.

I had the same issue. I was running E85 for a while, with it IAM never dropped below 1.00. After flashing to the 2.0x 91 map, it stayed at 0.88.

After putting on my high flow catted front pipe, the IAM dropped as low as 0.46 at one point on the 91 tune with Shell 91. It now hangs around 0.58. I'm going back to E85 as soon as possible.

as the other guy said try different brand of gas you can see the fbkc and flck knock all over the place. Its going to come down to finding a better brand of gass runing better octane fuel, running octane booster or pulling some timing out of the map see links below

Yep, pretty darn sure we've briefly seen each other before! Damn, just filled up this morning again (figured it might have been a bad tank before), but I'll certainly try Chevron or Shell. Thanks - see ya around!

This has happened to me twice as well..stage 1 93 oct tune.

My guess is the cold start routine is causing your issues. Generally speaking you shouldn't floor it during warm up or at such a low RPM. As Kodename47 suggested, full throttle below 2.5k is not a great idea. If you need to accelerate from that low an rpm at least slip the clutch little to bring the revs up. Its not a V8.
