Who In VIC can remap RB20DET ECUs?

[drunkenmaster]

Guys,

Does anyone know someone in VIC with the experience/facility to remap the RB20DET ECU in real time?

I think this may be the only way to get my RB30DET passed engineering.

Thanks.

Dr drift.

his on these forums.

dr drift @ xtc can

Thanks guys

I can, but I refuse to be responsible for your car

Unfortunately Sam's the only one that will lol. Just make sure you get dyno time too and not just a generic map dump based on your mods.

[drunkenmaster]

Yes, well dyno time will be a must to see how the ECU handles the extra displacement of the 3.0L.

I have been in touch with him and look forward to progressing further with it.

The next question is of course, what are the short comings of using a remapped ECU over a good aftermarket ECU aside from extra outputs and traction control etc i.e. stuff I will not use in my 70's Z.

a/m ecu may cost more but it does have a resale value.

[drunkenmaster]

hehe...like the one in your signature you have been advertising for as long as i can remember?

Sorry, just kidding. I couldnt help it.

Price of the ECU doesn't matter, my car and most past 1974 are ADR27a compliant and as such will not comply to ADR's with an aftermarket ECU. I have spent to much time and effort on my car to have it not fully engineered and roadworthy. If I wanted a power FC, I am currently living in Japan and they are not hard to get.

Thanks for the input anyway, more is welcome guys.

Are the R32 RB25DE ROMs equally as remappable as the R32 RB20DET and just as suitable as each other when remapped to run the RB30DET?

[jaik]

I beleive the A31 RB20DET ECU is inferior and old school (R31 red top RB20DET sensors etc) and cannot be remapped. Can anyone else confirm this unfortunate finding?

i've taken a eeprom dump of my old man's RB20DET ceffy, and its addressing is virtually identical to mine (allowing for the fact that his is automatic, and mine's manual). I have the series 2 R32 ECU, along with the sensors, and the PTU off a GTR and Series 1 R33 GTS/GTSt's. I'd assume the GTS25 R32 ECU is the same as mine since it would run the same PTU etc.

[drunkenmaster]

could you explain:

PTU = ?

GTS25 R32 = RB25DE ?

and then it would make more sense to me, thanks for the info

I picked up an R32 GTST Type-M ecu pretty cheap today, but the problem at home is I have RB25DE sensors and loom. I have heard people have trouble with this combo but i have no concrete info. It is going to be pretty hard to find the GTST EFI loom and sensors for sale on their own I imagine.

[funkymonkey]

PTU = Power Transistor Unit (basically controls your ignition)

GTS25 R32 = RB25DE R32 yes.

With the Type M one, if its a latemodel one (post 1992 to be sure) post Aug 1991 if you wanna take a gamble, it should work with the GTS25DE engine. But then again, without looking at the maps and the actual circuitry I can't tell for sure.

If I was you I'd get an absolutely early model (read 1993) R33 GTS ECU. It uses a PTU exactly the same as an R32 GTS25 wheras the later ones fromt he R33's have a smaller module and most of the control work is done within the ECU.

[drunkenmaster]

Interesting...Maybe I just wasted a little bit of cash then.

You dont by any chance have a way of working these things out by the model/serial numbers do you?

Ah geez, I just realised that in my haste I dont know if my ECU is from a AT or MT R32. I have searched the serial number and can confirm it is a Type M but cant confirm AT or MT. Bloody dumb move.

It is a 23710-11U00 MEC-R212 ECU if anyone knows

EDIT: Thank god, acoording to this site:

http://www.hks-power.co.jp/products/electr...on_sz_data.html

its a 89-93 MT ECU. I want to confirm though.
