4.0l?

Thank you

Since HPT hasn't given us access, what software can I use to read/write the TCU? Curious to check out the tables in there.

Thanks

That's the dream!

Even the car's own computer can't stop the raw German power. :)

Try lowering the 1st gear tq limit under tq management...

You're going to need a sticky tire on the street - there's no way around it. An LSD would help, too (I have one but haven't installed it). My best 60' on the street is a 1.95 on R888R tires, but...

Good kill vs the bike 🙂

Our cars have wideband lambda sensors from the factory fyi. They are read as WB EQ 1 & 5 (bank 1 passenger side cyl 1-4 and bank 2 driver side - cyl 5-8) Also you should...

The 1/8 trap speed should be good for 120 or 121 in the 1/4. The 7.95 ET would probably get you about a 12.1 in the 1/4. You'll need a better 60' to get in the 11s, I think. But it looks like the...

What did you run in the 1/8th?

Are you tapping on the "Go" tab in the app?

I've seen 1400+. If your lambda looks good and there's no KR, probably the only concern would be the catalyst material.

Dragy is quite accurate, always well under a tenth of a second off in my experience. I just reviewed some VCM scanner logs from the drag strip and it was kind of a pain to match up with timeslips.

Unbalanced fuel trims often point to injector issues on these cars.

EGT is read from the wideband sensors.

If so, what software would be required?

This is looking more like high pressure pumps to me. I have a log very similar to yours back when 1 or both of mine were failing. I replaced them and it resolved the issue.

Sounds like a delivery issue. The factory system can handle more than E40.. especially if the meth is adding a bit of fuel.

Interesting...will check my logs

The tables are of MAP in kPa, with rows being IAT and columns being ECT. I'm logging fuel trims with the same row/column values but not sure why they don't go up to full operating temperature. ...

Bump for speed density tips. Would like to understand how to tune this section.

Main goal is to fix a lean condition and ensuing high STFT (at idle only) running E85. Adding fuel under injector...

Are your LTFTs good with that .02 slope?

Hi Chevota,

Your attachment code got split up - the first bracket needs to be touching the word ATTACH.

I've never changed the normalizer. But interestingly, increasing the inj...

Curious to check out an AMG GT file if anyone has it.

Thanks

Yes, opening delay.
