Ctsv V2 E50 Tune

[ctsv2011]

2011 ctsv v2
intake pulley exhaust
91 octane tune

looking to get a few more hp from trying to run some ethanol
if i get my tank super lower and pump E50 into the tank and change stoich to 11.79
everything else should fall in line? looking to spinkle timing in up top and test with draggy

just looking to get some more power on race day car would be putted around town to run rest of e50 out then back to regular tune
yes i know flex fuel exists just looking to shut people up on the weekend

don't worry too much about timing ethanol dosnt always need more just the use of ethanol with same timing will increase power, if ur not going to use flex then yea adjust stoich to suit the mix in the tank, best to have WB so u can make sure OL is correct after as well don't just reply on guessing stoich

[ctsv2011]

OL? yea i have a wideband to monitor afr

[07GTS]

open loop or PE make sure is still same as before after the ethanol, just so u know ur good fueling wise as guessing a stoich can have some error if injector data is off, and CL should be same trims error as before

[07GTS]

u should get use to Lambda too of ur issuing ethanol makes it much easier then afr

[ctsv2011]

car is pretty dialed in targets .82 lambda. so in ol aka wot it should still target that .82 lambda on e50 correct

[07GTS]

yes as long as u have adjusted stoich to suit the ethanol mix
