Sorry such a dumb question, what's the effect of changing pid gain from 12 to 25?

Actually I'll update the first post. Prefer a lower PID gain and higher FF value in the logs I've seen so far.

Terry, I ordered the EWG on your web-site and it's installed but nowhere it's mentioned that I needed the FF wires. If it's always required with the EWG harness why didn't you bundle them?

Hey guys still waiting for more logs to come in on the latest firmware with a pidgain = 10 setting. Keep it rolling. I have some interesting updates planned but want to see the data before making any addl changes.

For the EWG logs it's easier if you just email them to me. terry@burgertuning.com.

Perfect guys, I think I have what I need now. I'm working with a couple guys who have noticed a little wobble or stutter at very low throttle cruising along. Might be during slight throttle position changes. If anyone else has encountered that and can capture it on a log it would be useful. Thx.

FWIW, I was running PID gain of 25 on 91 octane in Map 1 and 96ish (100 octane mix) octane on Map 2, and now 91 octane back on Map 1 with PID gain set to 10 as of two days ago. Not a single hiccup with any combination.

Ours runs great too. The key with these things though is accounting for all the variables. Modified exhausts, different climates, different trans types, sport mode settings, driving styles, etc. It can be a real headache to ensure every possible situation is tuned perfectly.. But it's a labor of love.

Terry,
I had that for a couple of days only cruising on the highway with a steady throttle around 2.500 rpm but haven't felt it the last week. The strange thing is it went away if I changed from comfort to sport +. I thought it was due to different gas as it started after I added 102 RON - I'm back on 98 RON and it's gone.

Awesome Terry !! In % how much fuelling can the stock pumps roughly handle in % targeting richer mixtures ?

I don't know exactly... Right now fuel pressure is dropping at higher boost levels causing more than one variable to change as I evaluate the fueling limits. To further development on that front I'll be installing a 255 inline soon.

The long and the short of it, I think, is with pump gas or race gas this AFR enrichment method (adding say 1pt to the AFR) will be OK to 400rw on the OEM fuel pump... And with 30-40% E85 it probably only up to 370whp. But, with the E85 I suspect EGT data will show no need for the richer targets. And with an inline fuel pump all numbers may go up. In a perfect world we'd be able to get AFR say 1/2pt richer using 50% E85. That may not be possible though without a back end flash map.

So the general recommendation at this point in time (for EWG, N55, F22) is PID = 10?

Should we be expecting a firmware update soon? Expected changes... driveability, performance, both?

Hey guys,

Posted 2.8 in the first so I can get some logs and data in on it.

v2.8 Firmware

1) Additional changes to the PID/FF logic. Will require FF to relearn when loading so ignore the first few logs post update. Pidgain = 10 is suggested.
2) Changes to low throttle mapping.
