VR-4 EEPROM / Need info

[Dasithkg]

hi guys,

i did some research on the net and came up with some Data.... just need to comfirm them.... so telll me if they are right or wrong
(did a search on this forum and came up with a shit load of WTB eprom threads... )

here goes...................

dual board ECU's are the older design.

MD 128618 is from the original vr4 and its dual board. (found one of these on trademe for cheap.. was thinking of buying it, hence the research and found out its the older design and pretty much undesirable).

Most EEPROM Ecu's are single board.

the dual board Ecu's that are EEPROM cannot do datalogging.

All A-Spec ECu's were single board EEPROM.


so are these info right guys?



cheers

Dasith

Your research is pretty accurate.... I reckon I have seen some early ( pre mid 1990) Aspec with a dualboard, but generally they all have eeprom single boards ( "5810").Good luck finding one , and then one that hasnt been damaged by leaking capacitors !! Some of the facelift Jspecs have eeprom single boards ( but not all are eeprom) .

thanx for the confirmation mike... who knows... i may have already stumbled across an eeprom...

Hey dasthigk do you mean E[sup]2[/sup]PROM as in Electrically Erasable Programmable Read Only Memory (EEPROM)or just standard old single shot UV ones (EPROM)?
I was wondering myself a while ago if E[sup]2[/sup]PROM's would work in our ECU's but I didn't really give it much thought apart from wondering why no-one has done it before lol cos it would be easier than taking them out and UV erasing them, maybe even comparable to flash memory like ECMlink uses....? Not real sure about that last one, maybe someone else that knows more about the subject could chime in?
Do you mean to say you might have found an EPROM?
I'm not sure what exactly you're after but I should have a couplle 512kb EPROM's you could have for nothing if you wanted them? (They're actually made by SGSThompson which are exactly the same ones MMC put in them lol what a coincedence).
Do you know how to edit the Hexadecimal code inside them? If so, please teach me!! haha

P.S - I forget his username but there was one guy one galantvr4.org.au who managed to get a dual board ECU configured for datalogging. Not sure how he did it though..

Yeah if your car has a single board I'd stick with it. Just make sure if it's an A-Spec you get the 810(A-Spec) instead of 808 (RSVR4). I'm not sure if there's a way around it but I couldn't find any info on how to get the ABS to work with the 808 in an A-Spec (even after doing the pin swap).

Hi mate..

you just managed to confuse me completely......... :mellow: so now there are 2 kinds of eproms...... crap... this keeps getting compliecated B)

i was talking about the eprom ecu that can take a ecmlink chip...... the regular kinda eprom........

thanx for the offer of those freebee chips..... but im definitely positively certainly sure that i dont know anything about those hexadecimal stuff you're talking about


cheers,
Dasith

 

[Dasithkg]

Any one can shed any light on this?


hi all,,,


is the following ECU outa VR4 and Eprom or not..

apparently from a Facelift Model

MD150427
E2T36173A
9630

WHAT IS THIS 9630 ? couldnt find that in any forum or ECU refference

Single Board or Dual Board?

info i found so far,

10/89 - 07/90 Facelift Jspec Galant VR4 (Manual) E39A-0014000+ SNPF 220(161.7)@6000 rpm 294Nm @ 3500 rpm MD150427 5spd 3.545 TD05 14B 450cc Y 1340 kg Facelift VR

10/89 - 07/90 Jspec Super Galant VR4 (Manual) E39A-0014000+ SNPF 220(161.7)@6000 rpm 294Nm @ 3500 rpm MD150427 5spd 3.545 TD05 14B 450cc Y 1380 kg Luxury Trim VR4 (Leather etc)

10/89 - 07/90 Facelift Jspec Galant VR4 RS E38A-0###### SNPF4 220(161.7)@6000 rpm 294Nm @ 3500 rpm MD150427 5spd 3.545 (LSD) TD05 14B 450cc N 1300 kg Lightweight RallySport version (Windup windows, no climate control, no 4WS, later ones have RS-E driveline)

Ahh ok, now I gotchya man. I was talking about something else completely.

And nah there's only one type of EPROM VR4 ECU, as in single board.

Yeah sorry man I was confused too! haha

Honestly though if all you wanna do is find an ECU that will take ECMlink I'd go -

A-Spec = 810
or if you got a J-Spec go for the 808.

Most commonly available ECU's you'll find for these cars and both will work with ECMlink.
Alternatively if you have a single board that isn't an EPROM type, ECMlink do offer conversions..

 

[Dasithkg]

A-Spec = 810
or if you got a J-Spec go for the 808.

thanx for the info mate..

now that 810 and 808. which part of the code should those 3 numbers be?
is it a part of MD ........

or

E2T36173A

or a part of 9630 etc...
number sequence?

 

[GVR40]

it will be in the md number eg md156808

 

[Dasithkg]

it will be in the md number eg md156808

thanx mate.. much appreciated.

 

[MDK87]

He meant MD165808, and obviously MD165810.

EDIT: Haha eyy! Hyundai's can fly! I thought I proved that!
Lol nice one Tim

 

[Dasithkg]

yep got that! thanx buddy!

 

[ctrimble92]

I'm also looking for info on getting an ecmlink set-up in my car.
Having trouble getting info and making sense of the stuff I can find.

I've got a HH aspec. My ecu has a mitsu label on the top cover that says-
MD165810
E2T37378
0710 E

The number on the wiring harness connector is 7378E

I believe its a 1g eprom, has been serviced in '03! Sweeeet Looks like the caps where replaced.

I dont have an OBDII port in my car from what I can tell, and presume I need one for ECM link. Would that be an issue?

Help from guys that have an ecm link setup would be very appreciated


Chris

 

[provan]

the obd port is next to the fuse box under the steering wheel
and im pretty sure the 810s will take an ecm chip

 

[Fugitiv]

Drop Tom a line from ecmlink they may well have spare boards they can supply you with... at cost to you of course.
Let him know your numbers and im certain he'll know.

failing that, disconnect your battery, pull the ecu and check...

Have a look here... Socket info

 

[ctrimble92]

I had already asked Tom about it, he said he 'believes' the a-specs ecu is the same as their 1g eproms.

About my diagnostics port- I have what I think is an OBDI (definately not the current international standard diagnostics connector- OBDII)
It only has 6 wires and 6 pins inside the connector.
The connector has sockets for more pins, maybe 12 or more all up, but they're empty.

. . . . . . . . . Do you guys have a 16pin OBDII port in your cars?

Its no problem at all fitting ECMlink to ASpec "5810" ecu's. I fitted and tuned numerous ECMlinks to ASpecs, including my own.
The US 1G is identical to our "5810' ecu. In fact, the US is where I have sourced a few ECU's for our VR4s.

Regarding the OBD1 12 pin plug by the fuse box.... the ECMlink 1G kit comes with a cable that plugs into that port to enable tuning comms.
Our '88 - '92 model VR4's precede the OBD11 ports and protocols.

If in doubt over ECMlink, PM me... they are by far the best way of tuning VR4's, CC GSR's and Evo 1-3 !

Cheers Mike

 

[ctrimble92]

I think I've found most of what I needed to know, thanks dudes!

Its good to hear someone who obviously has a fair amount of experience with ECM Link saying its the best way to go Mike. I was beginning to think an aftermarket computer would be a better option as there is a lot of people seem to go that way, but this seems easy and cost effective enough to win my interest.

I've tuned and set up most aftermarket ECU's, and believe me , it would be a backward step not to utilize the Factory setup .... unless there is a pretty good reason like 500 kw plus at the wheels . I doubt many people would be going near there... and I havent had too much trouble chasing the power numbers on a stock Mitsubishi ECU.

Ecu wise, our a-spec is pretty much identical to the us gvr4 and 1g dsm.

ecm link is your best/easiest/cheapest option. You still need a wide band O2 or access to one to check and tune your afr's correctly.

As a side note, eeprom's work fine in our ecu's and it has been done before, some still offer the "chipping" service. The ostrich and dsm/ecm link took over for the obvious ability to tune on the fly without having to write another chip each time you change something.
