To: Cobb,

With v402 e30 map, ive been getting some overboost/throttle closures followed by slight timing corrections which i believe are related to the overboost condition.

Will updating to v403 potentially help smooth out these overboost issues?
Did Cobb adjust WGDC in v403 to smooth out overboost conditions some users have been experiencing?
What other changes were made in v403?
I plan to update but some other users mentioned they "feel" the car is "slower" with v403.
Thanks Cobb! Love your product!

Give it a shot and see for yourself. It can't hurt.

Im running stage 1+ with fmic. 08 e92. Stett dci, helix bov, ets 5 fmic so far. An hour ago ago i wot once to race 12 sti stage 2 and i got a p30fc code which boost leak. I cleared it and wot couple times more and does not comes on anymore. Could it be i have stock charge pipe? Is this could be just one time warning code or something?

It is possible that it was a one time code and it won't come back. You should wait to see if the code pops back up and then if it does you should start looking for boost leaks.

The only changes made were to the WGDC table (a total of 4 cells) to correct the throttle closures we had seen from a few customers. This revision seemed to clean up the issue. Its possible you could still have some throttle closures if your wastegates are particularly tight, but those could be corrected in ATR or by your local ProTuner.

We did include a new section in the tuning guide ('Help' in the Help menu in ATR or on the website) that talks about how to modify the WGDC table for overshoots.

Glad you're enjoying your AP!

It's possible that you have a loose connection from the FMIC install. Also possible that your OEM CP is cracking or the OEM DVs are starting to leak boost. Couple of possibilities but if it doesn't keep coming up, you're good.

yeah i did some research just now, i think i will be alright. if i get it again i should start looking for leaks tho.

Yea, leaking DVs are hard to determine (basically have to spray water on the connections & look for bubbles). My car is my DD & once I cranked up the boost to 18 psi, I upgraded the DVs (Forge) and CP (ER) to ensure nothing broke & that the car wasn't down for service/replacement parts.

i see, my car is also my DD so i should start look for DVs and CP for myself concern. never knew that DVs and Charge pipe is that weak with stock. thanks for the tip

NP -- I mean they are plastic. Some people get lucky & they never leak, other people not so much. I just wanted to avoid them breaking & if you lose the C-clip on the OEM CP if it breaks, you have to buy a whole new CP just for that part

Here is a log from tonight.

I'm running a 50/50 E85 & ACN91 Mix, which makes approx 47.5% ethanol on the Cobb OTS Race v403 E-30 Map.

I have adjusted the fuel scalar on the OTS Map to be 44% ethanol (to be safe, because with E-85 it can be anywhere from 70%-85% content).

Can someone please take a look at it and let me know if things are looking good.

I see some timing adjustments at about 3k, but it stops at 4k (which is when the car really feels like its pulling & at the heart of the powerband). Is it bad if I keep running this map & ethanol content with these -3 degree adjustments? And if so, how much harm is it putting on my engine.

Thanks everyone!

Log looks good!!! If the timing corrections look like that in all the logs i wouldn't be concerned one bit.

Nice!

for shits, run S2+, with the cold weather you are less prone to heat soak with the stock intercooler. but watch your IATs. But with 91 you will still have to mix min. 3 gallons of E85 to compensate for the 93 octane. your E30 custom MAP is still more performance over S2+.

[benzy89]

Figured I'd just share the number from my ProTune done by Jake@PTF

• Stock Baseline with Installed Mods: 270 WHP / 290 WTQ
• 93 Octane ProTune: 380 WHP / 395 WTQ (Delta Over Stock: 110 WHP / 105 WTQ)
• E85 Blend ProTune: 428 WHP / 460 WTQ (Delta Over Stock: 158 WHP / 170 WTQ and Delta Over 93 Octane ProTune: 48 WHP / 65 WTQ).

Loving the power & it's actually me considering a Race Gas ProTune just because it's easier to get VPxxx then E85

Nice Numbers, especially with baseline with Current Mods. If it was bone stock, even greater delta's. Mustang Dyno?

How's your launch? 0-60 ft. just a bit more power....

What map should I install?my upgrades are BMW performance exhaust and afe intake.

Stage 1 Drive or Sport if you are using 91 octane, Stage 1 Aggressive if you are using 93 octane.

Dyno Mite dyno? Still haven't gotten around to 1/4 times so I have no idea, but I think I might get Jake to make me a Race Gas Map & use that instead (E85 isn't convenient enough & without an ethanol sensor, I don't like guessing the %)

I know what you mean by guessing. E85 is within an arms reach for me and used it quite a bit in Sept. through End of Nov. I went back to OTS due to the weather, can't really enjoy an E50 Map in the rain. But as for my logs, they appeared to be consistent at fill up, but like you said, %'s is still guessing.

Race gas (100 octane) is near but at $8 plus gallon, no thanks.

I mean, you can buy guaranteed, quality controlled E85 from VP Racing. Which like I said is my concern -- At least with Race Gas, you know exactly what you're buying. Be a different story if we had an Ethanol Sensor & the tune could adjust accordingly.

Anyone using a mount or clip for Cobb ap when monitoring, like on AC vent?
