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! |

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! -Josh |

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.

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! |

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+.

Figured I'd just share the number from my ProTune done by Jake@PTF
Loving the power & it's actually me considering a Race Gas ProTune just because it's easier to get VPxxx then E85 |

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 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.
