Procede Racegas logs, 10psi with Timing Drops

elim11 · 12-11-2011, 12:23 PM

As suggested from forum members, I filled up with 100 sunco unleaded race gas mixed with my 91 octane. Octane approximately 94-95 octane.

Nearly FBO, except 2nd cats. 6mt Procede rev 2a. Ambient 58F outside. Tried both procede 7-11 and 7-29 maps. 10psi autotune off for both and 100% ign correction. Still seeing timing drops. Can we rule out the fuel now?

Map 7-11 log

Map 7-29 log

Did you reset All the adaptations before running the race gas. Go reset them and log again. If you didn't, Do you at least do a couple do WOTs to allow the ecu to adapt to race gas?

Yes all adaptations were reset ad a couple wot were done before logs taken.

I think you need to speak to shiv about this. 11 psi and your showing timing drops with race gas. Something is up. I have no idea what to even tell you and he would be the one to give you answers. I see people run 14-15 with perfect timing logs

enrita · 12-11-2011, 02:05 PM

you should add always CAN DBW throttle and IAT. also graph afr 1 and 2 on top of each other. Same with fuel trims.

cn555ic · 12-11-2011, 02:05 PM

Wow. I thought for sure it was your gas. PM shiv with your logs and CSV data file and maybe he can give you some insight, which he should help you since you have his tune.

chili36 · 12-11-2011, 02:07 PM

Why haven't you contacted Vishnu about this?

I will re-work the graphs and re-upload. Thanks for your input!

I will do that. It seems harder to get a hold of him. Perhaps hes traveling.

cn555ic · 12-11-2011, 02:31 PM

Enrita correct. Log IATs as it is also important. Doubt you are seeing heatsoak timing drops based on ambient temps but u never know

That sucks. I thought they're support was pretty good ?

Re-Uploaded with CAN DBW Throttle and AFR, Fuel Trims for bank 1 and 2.

7-11 Map:

7-29 Map:

Also I did a couple runs with autotune ON, 7-29 maps. 10psi & 100% ign corr start. max 12 or 13psi (I forgot)

elim11 · 12-11-2011, 03:00 PM

Why are the AFR between bank 1 and 2 so different?

They probably aren't. It looks like they are scaled differently in the datalog. You can confirm this is by looking at the actual value on the bottom left hand screen. To manually scale, just click on the channel and press the letter "P". Turn off autoscaling and set your desired min/mix values.

If you are getting knock retard at just 10psi running high octane, we can rule out the tune being too aggressive. Instead, I'd look at hardware at this point. First thing I'd do is change plugs and see if the problem continues. If it does, we just move upstream from there. Might even be a case of carbon buildup in your combustion chamber.

shiv, what is a normal value for knock retard channel/log? mine is all over the place

That channel is not functional. Which is why it's not a default channel.

Yep

There's no way you should have timing drops running a grandma configuration of the Procede lol. No one else seems to have issues.

So I'd say that you might be at the point where you aren't misfiring yet, but it might come soon. When did you last change plugs?

Plugs were changed 1000 miles ago at the dealer. I've never had any misfires, prior and after new plugs.
