I know what youre probably thinking, should have just done a S5x swap. Problem is I have an iX, which makes that a whole different ballgame than a simple swap. Not only that, but I do love the characteristics of the M20 ie sound, originality, period correct etc. Just got bored with the power, especially considering the iX drivetrain loss.
Build specs:
MM 86mm pistons 10:1
s52 rods
ETA crank
19lb injectors
Myster-E 885 head: IE rockers, ported/polish, schrick cam 284/272
Miller MAF/WAR (3" housing, don't know if it matters even though they call for it w/ 2.8 stroker. chip came flashed with a tune miller had of a IE motor with 9:1. Mine has 10:1, not sure how big a difference it makes.)
Now to be clear, yes, the car does seem faster, not as fast as I was expecting, and not sooner on the power band as I thought but faster. I recently took a road trip from Sacramento to Portland and back with out a hiccup, and dropping into 4th in some mountain passes was really fun.
Problem is, its just not as streetable/daily friendly as stock. when starting up in the morning, the idle will go up and down which is annoying, but what ever. The other thing I've not been pleased with is the way it easily stalls sometimes which can be frustrating when youre stalling in parking lots, not to mention random bogging, CEL, and when I have the AC on its still the same old dog as the stock M20.
I installed a wideband O2 sensor, and the numbers are fairly good, at least not dangerous, yet I haven't been able to do a real tune due to the fact that my version of Windows 7 doesn't offer XP mode which Miller requires, which is one of many issues I have been soured with my experience with Miller.
So heres my question, even if I can figure out a way to do a decent tune on my laptop (or having to find someone else's to use) is that going to improve those easy stalling, CEL, bogging issues? Is a dyno appointment necessary or desirable? I was just hoping a decent break in period would do it but I'm at about 3k miles on the motor now. Any good advice is appreciated, especially on the Miller tuning issue.
