TO4 on stock ecu-can the odds be beat?!
I know its not recommended at all............BUT(!)
could I just run low boost and retard the timing manually ,or with an MSD unit, untill I can afford a standalone, with my safc?
My turbo is shot and over 600$ for a decent hybrid seems like a waste when I could do all the work and labor to put together a T04 set up myself.
I know this topic has been beat to death(hybrid VS. T04), but knowing that I can do the install myself and can get all the parts wholesale (unlike the hybrid where Id pay retail) should I just do a full To4.

WTF? Why do people think the stock ECU sucks so bad? Dale Clark was running a T04 and Cartech FMIC, with S-AFC and AIC, and was making enough power to break the dowel pins seats in his S4 motor.
With the right TLAs and careful tuning, you can very much run a big T04 on the stock ECU.

Bigger turbo night mare.
How come you dont just get a Micro Tech ECU for your car at the same time???
Infact I cant see why most of you dont get one. They cost around the $1k aust for em.. About $500 US.
Easy as to install and now they have all the lap top gear for tuning as well.
Wouldnt take much to get the whole system sent to your door and install it yourself.
By the time you spend money up grading your standed puter and everything else to go with it you could have had a MT and rip all that polution **** out and over half the crap in the engine bay.
Was one of the first mods I ever did to my car before even looking at playing with a bigger turbo or FMIC's...
Something to think about guys...
Im sure I could try my best in helpping you get one at a damn good price sent to you.
(I sell Micro-Tech's here in Australia)

To each there own, but the amount of money that Dale has spent on three letter ecu add-ons you could easily buy a standalone. He did make a good amount of power though that is true. But after just starting to see the power of the tuning capabalities of the Haltech, I am very happy that I went the standalone route.

I'd love to see more people start using the Microtec. It seems like it works well and you have full tuning capabilites. I don't know if it has datalogging and some of the other features, but I'm not too worried about it. I probably would have already bought one except I don't see too many people on here use them, and most of them are from Aus.

True, Dale doesn't like standalones for some pretty odd reasons, but it's very possible to make very big power on the stock ECU, possibly for less money.

i don't see why u couldn't just keep boost low, the problem with the stock ecu is not being able to control bigger fuel injectors. If you crank up the boost, or go bigger turbo u need more fuel = bigger injectors, stock ecu can't handle that. But if you kept the boost low i don't see why u couldn't use the stock ecu.

Again, no. You can control any size injectors with the stock ECU and massaged AFM signal (via the S-AFC). Read up a little bit and come back, m'kay?

Well, with a 50% correction rate, 550x1.5= 825cc.
I'd imagine you could go bigger if you had a turbo that moves enough air, but then it isn't really tuning, its guessing.

Well, your calculation assumes a linear relationship between AFM signal and injector pulsewidth, which may not be the case. Remember that the S-AFC only modifies the AFM signal, nothing else.
That was the biggest reason he stuck with the easily-tunable 720s and simply plumbed two more 550s into the UIM (it's a hack, but it works durn well).

ECU
Micr Tech (MT-8), loom,handset and laptop chip with dongle... $1130 Aust.. = $565 US..
MT-8, loom and handset.. $1080 Aust. = $540US
MTX-8, loom, handset and 4 bosch coils... $1280 Aust. =$640 US
Plus postage on top of that.
The only thing is your stock ECU has to stay in the car in the ser 4/5. The ser 5 ecu runs your oil metreing pump and your aircon ,cruise and warning lights.
The ser 4 has a mechanical metreing pump.
The MT-8 uses the stock coil packs, were as the MTX-8 uses 4 coils.
All systems are used all over aust. Prob one of the best ECU's to use on a rotor.
Yes haltech, EMS and other brands have more functions on them but you pay much more for them.
I have had my MT-8 in the car for 2 years now and it rocks.. All the polution crap has been ripped out of the car so my engine bay looks neater. I am looking at upgrading to the laptop set up before Christmas as so my tuner can do a better drive tune with my car.
I will post up sum more pics of my car in a new thread tonight or eairly tomorrow morning so you guys/girls can see my nearly finished car.. Once done we are looking at over 300rwhp out of it.. Keep your eyes open for the thread...

The MTX-8 is the one.....
I hope to have it in my '90 vert in a few months (kids + xmas = broke ***).
QIK78U...question.
Do I have to use my stock TPS? I heard that the TPS is somehow integrated w/ the oil metering pump. Does the MTX have a load variable output that can be adapted to increase the pump output during load?
