I drive the car daily when it's nice, so that wouldn't be very good running E85 due to the fact I could get stuck somewhere with no way to get E85, unless I roll around with 5 extra gallons in the trunk...just doesn't make much sense to me, I would rather do things right the first time. And true, they're several high horsepower cars that run a Megasquirt and there is nothing wrong with a MS, BUT like I said, I have more capabilities with my current ECU.

Tuning rate is $200 an hr, full set-up of the ECU with flex fuel is $2995 plus the boomslang harness that would have to be made on my car, so maybe $3500 total + tuning, plus supporting mods=$6,000+ to lay down 600 whp. I could go all out, like 700+ whp but that means a new turbo etc, which is too much money. I don't think 700 whp would be very streetable in a car that is alittle over 2000 pounds lol, **** I don't even think 600 whp would be.

lol well I would want it to be reliable, so a built trans, DSS custom axles at least...
I mean, yeah I could actually put the car to 30 psi right now, just swap out fuel and injectors and make 600 whp but I don't know how long the drivetrain would last.

In my honest opinion I think its ******* retarded to spend that much on an ecu+tune.
Also you'd need to pretty much replace every single thing on your car with custom ****. diff/trans/axles/etc etc etc.
And for what? so you could spin til 80 like the 1000whp supra's? even with ridiculously low final drive you'd still spin like a ***** IMO.
its a tiny light car with a short wheelbase. getting loose at 100mph will almost guarrantee you put it into a post/tree/wall/other car

LOL, actually my car has really good traction it doesn't even break the tires loose in 3+ gear. Don't ask me how...
If I did decide to run 600 whp so I can run with the big boys I would be rolling on fat meats in the rears, 225/60/15 Drag Radials at least.

MS maps (tuning tables) are only 12x12 where as the PRO EFI are 128x128. Plus a bunch of other things the MS does not have, such as a built in MAP sensor with unlimited range, etc etc a MS would be a downgrade for my AEM EMS, let alone a Pro EFI ECU... It's so big though lol,
You can also have a MAP sensor that has unlimited range on the MS (there's no such thing but hey, they tell people **** all the time to sell them anything), but that loses accuracy so much, it makes me want to cry.
The MS3 also has the AFR and EGT Safety system, where it will activate a limiter if you go lean or hot under boost.
Oh, it's also $500, just saying. Save your money man, really.

128x128 maps are asinine and excessive, but a great way for tuners to rip people off I guess. 16x16 allows plenty of resolution to tune cars running 30psi without taking a decade to tune. With automatic extrapolation between cells there's absolutely no reason for that much resolution to exist. Even the 24x24 maps on the Hydra 2.6 cars are a little excessive IMO, unless you are running a LOT of boost.
The numbers are great, but IMO you should spend a lot more time focusing on mid-range torque, since you have very, very little of it. I'm making over 100ft.lbs more than you are at 4500rpm - that's really, really bad. I don't know whether it's the Kelfords or the super-short intake manifold runners or what, but IMO it seriously needs to be addressed before you talk about blowing another $5-6k on an ECU upgrade. I understand the 5857 is a big turbo but you should still be on full song by ~5000rpm at the latest. You aren't seeing the full kick of that turbo until past 6000rpm, which is too late to be usable.
Which one of these setups would you rather drive? Torque/HP are equal at 6000rpm.

It's not about how wide the tire is on drag tires, it's about how tall they are lol 60's are super tall. Interesting graph Sav what do you think I could do to improve this? Cam gears possibly? But, we also do different things in our cars I mostly like to do highway pulls/runs so higher RPM power is good for me, maybe this is why my trans has lasted so long? Also, your car was dyno'd on a dynopak the graph would look a lot different if I was on one of those, I would make about 40+ more hp then I did. But your car has to be a blast to drive with all that midrange power.
"The car ran perfectly all weekend, consistant 9.6's@147mph, which is pretty impressive considering all of the tuning was a few emails back and forth with Jason at ProEFI. The flex fuel feature is so nice! I can run the car full tilt nearly all the time, and not have to worry about octane. If I need gas and can't get E85, I can still put pump gas in the car and the computer will make the appropriate adjustments, no need to hook up the laptop or anything....just simple! I can't wait to get the race car to the track on this system." ......John Shepherd
I was told you do not have to make separate maps for fuels, just one.

Any chance you could post up a datalog from a full pull? I'd specifically like to see 2000-7000 rpm with log time, ignition timing, rpm, boost and afrs would be nice. If the shop shared the dyno config it would also be nice to see that. What tires are you currently running that traction in 3rd isn't an issue?
I also forgot to say this earlier, nice numbers.

I take that back, last night it was about 45 outside after 6,200 rpm my car would spin at the top of 3rd, 4th gear no tire spin at all, I think if it is 70 outside or above I wouldn't have tire spin at the top of 3rd. I am running Nitto NT01's in the rear at about 25 psi, with my KYB AGX shocks at #3.
