FAST XFI 2.0 vs. BS3

[Junkie]

Back on subject.... Who all local tunes bs3, that should be a deciding factor, 1 for hpp so far, who else? I dont care about what kind of numbers are made, I care about good driveability.

Exactly. Best local tuners for BS3 and FAST?

Will,I've had my hands on FAST, BS3, Megasquirt, and about everything in between. I am a huge fan of BS3 if it's in the budget. You can't go wrong. It's SUPER easy to tune and takes NO time at all. In fact, on Fast408's car. We often datalog just to check it out, we never edit the tune.Once it was on the dyno - I think the only thing we did after the fact was to do some cleanup.

I can only think of one problem, that was a random injector driver on Greenbullet's car - I think John handled that one pretty quick with a brand new board. The only problem bieng that it may be slightly finicky to the condition of certain kinds of LowZ injectors. We just switched to HiZ and got it over with.

Do you sell both systems?

Does BS3 offer auto tune, traction control?

No, I don't sell any of that stuff.

If there's an autotune feature, I've never used it - but of course, we do use close loop when possible. They do have a traction control feature from what I remember, but it's one of those things we don't mess with very often.

Awesome, thanks man. Right now I'm trying to find the best price on both systems. Should have something ordered this week.

The one thing about BS3 that really makes it better than classic fast is that you can change the injector offset time per voltage (as it changes) as opposed to classic fast only bieng set for ONE voltage. So, as the night goes on (at the track or wherever) and the battery wears down some, the voltage is decreased - but never fear, BS3 has scalable offsets. Classic fast, you have to settle for "what works". Fast XFI I can't be sure on.

I'm in the same dilemma, I've had problems with my 98 and the eec system. I'm stuck between getting an ecm for mine and going from the converted cop back to waste spark, or going with bs3, fast, megasquirt setup. The money is a big factor, but with this being the 3 motor popped in about 3k miles, it's getting expensive either way. Some of the motor issues lie from the original builder, major combination \ tuning changes, and (I believe) ecm problems for this last complete build. I killed cylinders 5, 6, & 7 in 500 miles of break in driving. Mild setup 9-9.25:1, navi heads, 96-98 cobra cams, 01 cobra intake (minor port work), Probe pistons, Total seal rings, D-1 @ 16psi. Timing and tune were done around previous build with a F-1a @ 21 psi. A\f were a little on the rich side with a slight lean spot on initial tip in.

Anyway, long story short. I need something that I can get a reliable tuner to work. I know there's a guy in tulsa for the Fast stuff. I've personally been in \ around a couple of his tuned vehicles and I'm very pleased with the start ups and driveability (my MAJOR CONCERNS).

My dislike for the fast (xfi is what I have experience in wiring on ford pushrod stuff) with the mod motor is the XIM required for multi coil, all the added features/functions that I wouldn't be using, etc.

I'd most likely go back with cams, maybe a sullivan intake, hpp upper, etc if I make the switch to aftermarket controller.

Fast XFI has this feature.

The new XFI 2.0 software is similar to BS3 the only place I feel it lacks is in the Datalogging. The datalogging works, but the BigStuff datalogging seems much more powerful and smooth and it integrates smoothly with the Racepac Systems.

[JETFAST]

all the fast systems i have dealt with have junk for a harness, and more junk on the ignition side. The big stuff 3 over fast system.

For the money and options, pro efi is where it is at. nitrous control, boost control, and traction control, extensive expandability are all standard features with the pro-128 ecu.

Everyone around tunes different. Find someone with engine building and ecu tuning experience, and go from there.

I heard PRO EFI didnt have live tuning capabilities, is that true?

You have to reflash the ECU more like a OEM style of Tuning

I vote this guy to tune the Bs3 on your car Will. He has the experience needed to do the job how you want it to be done.
