E-70 Tune
E-70 Tune
Hello All,
A customer of mine posted up this and I just wanted to share it. I have been working with Brandon for a couple of weeks going back and forth on this tune but I think we finally got it about right. Here is his post from the Alternative Fuel forum:
Just wanted to let everyone know about my new tune. I am running E-70 now with some decent results. Unfortunately the local gas station that sells the e-85 is down to e-70 since it has been freezing here in central Illinois, however the car is definitely faster. I also have ZERO coldstart issues with the E-70. I have delt with Mitch before and he is always very fast at responding and revising tunes via email. All you need is a laptop, a tactrix cable, a couple free programs and this email... Mitch@vividracing.com and your setup to make more power.
Anyhow my mods are in my signature, still on a stock turbo with 10.5 hotside. I am running 25psi right now, unfortunately that is about it for E-70. I am not running much timing at peak torque, which is why the torque isn't really high. However I am able to run more timing just about everywhere else, as well as still running a little rich. The afr's are 11.8 to 11.1 by redline(gas calibrated LC-1 wideband) The only thing I have added is a wideband and a set of Precision 1200cc injectors. Mitch was new to the gas and that big of injectors on the stock ecu, but he got everything to work great. The car idles/runs like a champ. I have a 93oct pump gas map for the bigger injectors as well, in case I ever go on a big trip where E-85/70 isn't available. Hopefully in a couple of months or less we will get the full blown E-85 back and be able to make some more power. The top end is what amazes me, even with the boost tapering down, the car never stops pulling.
Anyhow here is a DLL dynograph to get a guesstimate on power @25psi on E-70
The second dynograph is on a friends AMS GT3076r on pump gas @24psi (He is losing a little timing which caused the little dip after peak torque) Both cars are pretty much exact in mods minus the turbo/gas. The DLL runs were one right after the other, same smoothing/weight(both of us in the cars)
If you have any questions feel free to contact Mitch via email at Mitch@vividracing.com or me via email at gsxtremedsm@yahoo.com(as I don't check my pm's all the time)
Enjoy Guy's,
Mitch Mckee
