Aftermarket ECU and Piggyback list...

if you like doing things half-assed, more power to you.

Honestly, I get pissed when I hear this. I have a reliable 250whp car running off of the stock N/A ECU with a SAFCII. Thats all I have, and ever will have. So I really don't understand the ignorance. Half-assed is getting something like this then NOT tuning it. Even with a crap setup, you can tune for reliablity. Never did it not start, and never did I have any problem do to the tuning.

Ive said this before and will say it again ... there are different solutions for different problems.

You need to understand what you want and then go from there. If you want a drag strip only car, get a standalone and tune it for WOT. If you want a daily driver that will get you to school or work every morning try and stick to the factory computer - it's been engineered to run the motor in many conditions which are outside the WOT range.

EDIT: The SAFC is not garbge ... the SAFC is a tuning tool and if used properly will do the job. You just have to know its strengths and limitations as with anything else

fantastic answer........ makes everything so easy to understand

Many people who have standalones don't like the part throttle driveability because they go to the dyno and get "tuned" for wide open throttle and more or less call it a day (either cause that's all they can afford or some other reason). It could take most average standalone owners years of tuning to completely exploit all the capabilities of their computers on a given engine(especially when they are forced to develop their own maps). If you just spend a week on the dyno, you can/will have a driveable car but too many expect to just leave it like that and get better than stock quality/reliability and performance under all driving conditions.

Most people only have dyno jets near them which sucks ass for tunning. They are only good for WOT runs and getting HP numbers. Mustang dyno's allow you to tune under load points. Thats why their part throtle sucks. Short story, right dyno for right tunning.

what about MAP-ECU that corksport sells? it lets you get rid of the flapper and convert your car to a map system.

[Lex]

yes but it doesnt control ignition

[BuGS]

And it is EXPENSIVE!! Go with a new Greddy Ultimate, you can find em for $100 cheaper, and they control just about everything.

Personally, for our cars...323's, Escorts etc running BP or BPT/D's, you can't go past a microtech for bang4buck.

The other thing is, that has come up many times before is your dyno figure readouts...I'm not going to go into it, but what I will say is that I'd love to see what my car would make on where ever BuGs got his car dyno'd.

This is my current result with a microtech as the ECU.



Not trying to sound high on my horse, but there's alot more money under my bonnet than BuGs's, for a extra 10hp, it just doesn't make sence. Here in Aus, the Dyno Dynamic dyno's are considered as the "norm" or comparitive dyno across the country...but yeah, as i said, that's a different story. Microtech's are good! :D

[BuGS]

Well What I don't get is you guys keep saying there is a big difference between dyno #'s and whatnot, But 1/4miles times is what is surprizing. The puerto Ricans have the same dynos as us, and there is a guy in texas right now that ran a 12.7 on a N/A BP with 8psi out of a T4 67 trim. So he probably was only running 275whp or so. http://mx-3.com/phpbb2/viewtopic.php?t=50776 BTW he stats in his thread that he has had 450WHP on an STOCK N/A Bp block and internals. He was going to see how much he could get before it actually blew but after binding the engine when he installed his twin disc he dropped in his 2.0L stroked engine instead.

what im not understanding here ROB-80E is your dyno chart. is the lack of a TQ curve???? do you have a chart showing your ft. lbs? what turbo are you using with the microtech?

[ROB-80E]

Here's two setups for you showing tractive torque. It doesn't measure in ft-lbs, don't ask me why.

16psi, VF10 hybrid on GTX manifold, RX7 460cc injectors, Microtech, and all other common bolt ons.



19 psi (with spike right at the end), GTR turbo and manifold, 460cc injectors Microtech, 3" dump and all other common bolt ons.



These results were achieved on the same dyno and the same GTR head and block. The only things that were changed was the manifold, turbo and dump pipe. So really, this is a very good example of the difference in power that can be had from a VF10 hybrid to a VJ23 setup.
