Aftermarket ECU's

[Mr R32 M-Spec]

I was just wondering what computer people have got on there cars, I am planning to upgrade mine but am confused about what to get, there are so many different brands available

So what do you guys have (GTST's mainly)

cheers:D

[meggala]

I have a re mapped ecu

[Zensoku]

same here: Had my original ROM removed from my stock ECU and had a Chiptorque EEPROM fitted, retuned on the dyno and has had speed limiter removed, rev limiter raised and fuel cut raised (requested to keep that just in case a wastegate line fell off)

[Mr R32 M-Spec]

How much do your cars make now?

How much was the cost of a remapped ROM?$

[Zensoku]

Cost of the chip was about $500 plus the dyno time... now that i think about it now, Apexi Power FC's are starting to go real cheap, ($1300+) and that would be a better proposition now if i were to recommend something now...

I make 241rwkw in my R32 GTR which has the above mentioned chipped ECU, full upgraded exhaust from the turbos back - HKS dumps, Apexi front pipes, and a custom 3.5" Mandrel bent exhaust, K&N Pods and boost spikes as high as 16psi with standard turbos using a bleed valve.

Mr R32 M-Spec,

Try emailing Lucas from Perth ([email protected]), he has many maps for many cars and can reprogram ROMS to your specification. His SR20 "BikiROM's" have been selling like hotcakes lately, now shipping them to workshops overeast.

The RB20 computer is really easily reprogrammed so its probably the cheapest option and still allows alot of scope for increased horsepower.

Im not sure about cost, but ill bet its cheaper than Chiptorque.

or you cna contact dr_ drift in melb he has doen mine and a number of other r32 ecu's btw my results are in my sig

There is only one ecu that you should be buying and that is autronic with its V8 supercar track record nothing else comes even close to it.

they ahve their good points but are still not legal you get caught with one an you are owned plusa the cost of instalation and tuning is very high.

plus why go after market when the factory chip can be reprogrammed?

The V8's use an M48 motec...

[Roy]

Woops, poor Autronic got reamed, control ECU in V8s means all car are now using Motec.

Oh and despite many teams using Autronic when the rules allowed, not many of could afford the SM2 with all the fruit, just like many of us cant afford an M800 Motec ECU with all the fruit. (Thats an assumption that they use the top models)

Mort, have you set up any SMCs on RB20s?

[kjb_r33]

they use the M48, all owned by tega, maximum of 1 igntion output and all they can change are fuel and ignition maps, pit lane limiters and so on are all programmed by tega, who can ask for the ecu and replace it with another with no warning

[Roy]

So the control ECU has limited the teams ability to use many of the other features? They still get all the data logging dont they?

Im assuming they are still able to trim mixtures etc for individual cylinders etc etc. Tega i imagine are pretty paranoid about traction control and the like.

As for the ECU im using, well at the moment factory, but i took the easy road and after a lot of patience and delays i get my Power Fc this week.

[browny]

Roy, Out of interest where did you get the PFC and what was the damage?

[Kdawgboostin33]

I have recently installed a Haltech Engine Management and am having difficulty with coils, etc. Is turning out to be a very expensive exercise. So i would recommend a Plug in or even Chipping, would be the best option

[rs73]

Is it worth paying the extra cost to get both powerfc & the hand controller? As most tuning workshop who can do powerfc should have the hand controller, once it's set nice, do you need the hand controller yourself to change something from time to time?

[GTS-t VSPEC]

One of the workshops in Perth borrows the dataloggit to do the tuning of the PowerFC, provides more features and is much quicker to tune then using the hand controller.

I have the Wolf 3D Ver4 Plug'n'play computer in my car. It's been great and has lots of advanced features that many other aftermarket computers don't.

[Jaws]

power fc would be on the top of the list for me, just plug in and they come with a base programe that gives more power with out being tuned then just drive to your dyno place and get them to tune it. i guess you would save money on the fitting process as well motec make a plug in as well that is sposed to be good.

I have been looking into the autronic smc and sm2 and both have the "autotune" option which is most valuable if u want to drive it to the tuner to have it further fine tuned.

http://www.autronic.com/autotune.html

My only concern is this:- "After the tuning is complete the analyzer and 02 sensor is longer need. At any time after tuning is finished the values in the target closed loop table can be changed, and the engine will automatically run the new air fuel ratio"

using the o2 sensor continously would be more ideal.

Has anyone heard of running the autronic with an o2 sensor (closed loop).

The cheapest PFC and controller I can find brand new is $980 and $355 respectively. And that's delivered. Pretty good value I reckon. Try www.greenline.jp

This is also the price I got, don't forget postage isn't included.

I have been reading up on the FC and have found limited info, so far i've found that the FC when tuned on pc is only available in japanese, I have heard rumours that there is an english version available but havent been able to find it.

Any ideas on this?.

Also can the FC be used without numerious features that are on skylines like air con etc..

I would like to use the fc in a car that was originally carby and doesnt have air con etc.., anyone know just how flexible the FC is with this kind of thing?.
