A few months back I started the e85 conversion for my viggen. I did the injectors, fuel pump and ecu tune. I took it to the dyno and it showed waaaay to lean, but power was very smooth. I sent the ecu back to have some fuel added. I then realized my maf was original at 82,000 miles and should be replaced. Fixed my lean problem, but now had to have my ecu retuned, again, to the original "leaner tune." Car runs great. My wideband shows 14.5 at idle and 12.5 under full boost in fourth. Perfect!!!
I have to say thank you to John at JZW for all the patience and I'm sure at least 100 emails by now and still not one phone call. I sent the ecu back three times and he never once complained, at least to me.
I just finished a 250 road trip with cruise set at 80 mph and got 22 mpg. Eh not too bad.
