Does this look right for e85 tuning?

[thereason]

Had someone tune my vehicle on e85, I trust him and trusted him, but something just doesnt seem correct about my Stocih AFR, he said its suppose to be doubled due to the addition of the e85 content once the tank is filled but something just doesnt feel right about this. Or maybe its just me?

[mowton]

need to see the tune file but doesnt seem right to me.....

not right

Guy should google stoich of e85.

Guy should read a little more.

Then stoich for E85 is like 9.7 The technique I believe he is speaking about is how you can alleviate the IFR maximum ceiling (i.e 63.5lb/hr), to run bigger injectors. Then you double the stoich (of the fuel you are using) and cut the IFR (of the injectors you are using) in half.

Were the injectors changed in this upgrade?

They were mowton, from whatever factory was to FIC 1000's.

What year and setup?

Is it flex fuel equipped (cant see the 85% cell in the attachment)? If so, then again the stock IFR would need to be cut in half.

Did he tripled the stoich and cut the the id 1000 injector rated flow of 114 ib/hr in thirds or like 38 lb/hr.?

I'll post a couple more screen shots of the tables as soon as I make it to my PC. I do thank you for you help and responses by the way.

For people who were quick to crap on the stoich table, I'm guessing most of you have never use that to be able to run injectors that go beyond the factory IFR limit. The stoich table is adjusting with alcohol content, which is normal.



That said, on a 2009 CTS-V and those injectors, there should be no need to scale the tune in order to run them. If your tuner did scale for those, it's not really causing any problems.

I do understand, thanks Dave. Greatly appreciate your input. And with your signature be said, ill post my file. My initial cold start is off, I've tried everything possible from adjusting injector flow rates to whatever else idea popped in my head, the problem; on cold start, the car sputters and lags greatly when throttle is applied, after a few minutes its fine, but its slightly worrying because when attempting to pull out of traffic or get on it, the car will barely move or sputters and moves wacky. What all is wrong with this file?

Who crapped all over the stoich table, eventually, without much help other than a half a .jpg picture stated if flex fuel capable, then the IFR would need to be cut in half....I shouldnt have used the term stock, which i was alluding to the ID1000 value, taht was my bad...

If not then i sumised that the 0% stoich value would be like 1/3 of E85 stoich.....assume if you can cut them in half and double, you can cut then you could triple and cut IFR in 1/3's.

I have a personal rule of not supporting FIC equipped stuff (and that's for either FIC). Sorry. If you're having cold starting issues on ethanol, then it's in the tune most likely.

No problem, thanks anyway.
