microtech ecu
|
Wed, 29 June 2005 04:01
|
 |
hey i have recently bought a microtech ecu, its programed for a 4age and i have a 4agze motor
i was jsut wondering if this needs to remaped before i can use it, if this is the case can any works shops change it or do i have to send it to mmicrotech
the ecu is a mt-8 series 2
any help would be much appreciated

i'd say yes it would need remapping, since the 4age is NA and the gze has boost 
the current mapping wont know what to do once your engine hits boost, prob lean out and explode

explode hey, hhmm better get it changed. um can tuning places do this or only microtech themselves, i really really cant affored 300$ or waht eva to get the mapping changed

you will have to spend $$$ to get your ecu tuned unless you dont mind having to spend $$$ on getting your engine rebuilt.
spend the money a properly tuned ecu can make the difference between success and a big mess

yes i know i have to get it done but do i have to send it to microtech or can a tunig shop do it, the car is going in on friday to get rewired adn ecu installed so i dont want to have to send the ecu away

to answer your question:
you do not have to go back to microtech to have the ECU tuned, any tuning shop familiar with microtech will be able to tune it for your ZE.
BUT! If you have taken the microtech from a 4AGE using a distributor (as all the 4AGE's did) and plan to run it on a 4AGZE with crank angle sensor you will have problems as the ECU's are configured differently for each setup. You could convert a crank angle sensed 4AGZE to distributer if you needed to though to get around this problem.

a distributer runs off the camshafts on the right hand side of the motor at the front. On the 4age's the ignition leads that go to the spark plugs connect to the distributer on some of the gze's they use a crank angle sensor which is in the same position as the distributer but the ignition leads do not run from it instead they run from coil packs...
i hope that clears it up for you...

why not use a stock gze loom and computer they can support up to 14psi (ive been told some people are running more) and you wont have to worry about getting it tuned plus it will be more legal than running a micrtech

The stock ECU does work well, I ran mine with this for a while and it was fine, I ran 14.5psi and it was good for about 145rwkw.

i was jsut told that if i wanted more hp and the car to run better that i should get an afrter market ecu, the ecu that is currently i nthe car is a 4a-gz so i assume thats a the 4agze ecu, correct me if im wrong

yeah thats the stocker.. if the car is running ok except for beingrich and you cant afford to get the thing tuned and its running extremly rich i would look at things like the oxygen sensor knock sensor etc being broken/faulty.
The factory ecu's are supposed to be better for things like cold start, air conditioning etc etc which are supposed to be a problem to tune for in an aftermarket ecu

If the car is running a GZE even with a big pulley the standard ECU is more than adequate. I have seen on many occassions that this is good for about 90 - 100 rwkw. I have seen CLAIMS, of a little more power than that with aftermarket ECU's
How much power have you got and how much are you after?
Sounds like the person telling you that you NEED an aftermarket ECU just wants some dollars out of you. If the car is running poorly on the 4AGZE ECU then it will most likely be due to poor installation or dead sensors. A new ECU will be just as shit if it is not installed properly either.

the oxygen sensor knock sensor etc being broken/faulty i got no idea at wat i would start looking at. as for the prblem about ai con i dont have it so its all good, it seems to run good except thah its ritch and slow as shit but only cuz its got 4psi witch i will change with a boost controller soon

if you want more power out of a gze then an aftermarket ecu will definatly help as they tend to run rich.
however if you are being told an aftermarket ecu will fix your poorly running gze then that might not be true i would suggest looking for faulty sensors

That makes your setup a little clearer.
Most of what was stated above still stands though.
If the factory ECU is working properly and the sensors are reading correctly then it should only be power robbingly rich at wide open throttle, thats my experience with factory ECU on a turbo 4AGZE.

depends on what the problem is but spedo recalibration is a bit pricy from memory like 300-400 buks.
I can tell you how to check for error codes it might give you an idea of what broken before you take it to the auto electrician which will save you a bit in labour i guess

Don't seem like to much of a noob when you drop your car off to get the factory ECU "Tuned" as there is actually stuff all they can tune on them. Idle, base timing, some slight adjustments on the AFM (if it has one) is about it on a 4AGZE. With your turbo they should be able to determine the maximum safe level of boost.
I would say that you are really getting your car sorted out than tuned as such.

ok thanks
so the best thingto to rather then getting my microtech installed would be go get my wiring problem fixed and then to sort out the fuel and rev display. and to tell me waht the largest safest boost to run is.?.

Well it's hard to say without seeing the car, but it sounds like you have a setup that just needs a bit more work to have it sorted out. So this is probably a better option rather than adding a new ECU and potentially adding more problems if it's not installed or tuned well (just because someone is payed to do something doesn't mean it will be done well unfortunately).
Get it running properly, get the little annoying problems sorted (like gauges not working), once it's running get someone with an 02 sensor to check the state of tune it's in and to take work out what the safest maximum boost is that you can run. That seem like a logical process to me.

If its an MT-8 and not an LT-8 then Microtech WILL NOT reprogramme.
So this ecu is stuck on 4AGE forever.
So if you have paid money for it, try and get it back (the money that is), or sell it to someone running a 4AGE

No, changing settings like dizzy to coilpack can only be done by Microtech head office.
Any they stopped supporting the old MT series at the start of this year.
They now only support the LT series.
So unless you know someone at Microtech who will do it on the side, its stuck on its current settings for ever.
It can still be tuned, but things like ignition outputs, injector outputs, firing order etc, are locked.

|
The parameters within an MT-8 can be adjusted by a tuner with a handset eg. injector pulse width, timing, rpm limit etc.
If the MT-8 was set up for a car running a dizzy (4AGE) it will not be able to have its software that forms tha basis into which tuning parameters are made changed (I don't know if I explained that clearly). I am not sure if an MT-8 set up for a 4AGE would have a map sensor in it capable of reading boost?? Someone may know an answer to that??
I think this guy is now uber confused.
I think the best example would be that an MT-8 from a 4AGE could not be configured to run a 1UZ, but the same 4AGE MT-8 could be tuned to run a stock 4AGE or an UBER HI-PO 4AGE with wild cams, bigger injectors etc.

Yes, important. If your car has not got one and should have, that will cause issues with your 'tune' 
Here is a sample of what a toyota one MAY look like.

Some 4AGZE's run MAP sensor I believe.
Have a look for that.
Just has a small rubber tube running to it from the manifold, and 3 wires back to the ecu.
If you have a MAP sensor, you won't have an AFM
And the car will not run without an AFM.

it would be a map sensored gze as you said the car is working and its turbod so if the car had an afm it would be between the pod filter and the turbo. if it dosent have an afm then it would be map sensored as the car wont work without one if it was required
