Anybody happen to have ECU pinouts? I have a crazy idea.

Yeah +1 on that. Need them for an RSM

I was thinking Evo 7 ECU running Tephra :) I have all the Magna maps already and the Evo 7 pinouts :)

Workshop manual, It's all in there
Have found them when I was installing my double din unit with gps

Anybody happen to have ECU pinouts? I have a crazy idea.

The auto ECU pinouts are similar to the Evo 7 GT-A (I haven't confirmed everything, but a few key things check out). If you can find pinouts for the auto v6 Eclipses, those should also be close (If you do find Eclipse pinouts, I'd appreciate a pointer!).

The manual ECUs are pretty close to the USDM Evo 7/8 pinouts. However the manual v6 Eclipses use the same connector set as the Evo 9, which is 3 of the 4 connectors from the auto ECUs...

I thought of that quite some time ago. Unfortunately the ECUs used in all the 4 cylinder cars only have 4 injector drivers... and the PCBs are different as they don't have the space for the extra injector driver circuitry :(

You could flash your current ECU with the Evo ROM, but the code will only drive 4 cylinders. I've had it in mind to see how much would need to be modified to add v6 support, but lack the time at the moment.

I know they are in the manual but cbf looking through hundreds of pages of diagrams - I want a pin by pin list :P

Dean, I am not having ago at you so please do not take it this way BUT if you cbf looking as I did through the manual then dont ask for them. I did the hard yards and so have a few others

You can also do as I did and invest in some of the other manuals avail out there as they have a ecu pin out in them as well

Mal I posted this after searching through the workshop manual for over 3 hours last night. Note the post time.

This will be for a side project to see if we can get Brendan's wagon running on TH looms with an adapter harness and Evo 7 ECU.

Looking under the DPI pages in the circuit diagram section would be a good start
Not list but says what some of the wires do and pin location at the ECU

None of the manuals I have have a simple pinout explanation. It is all in circuit diagrams. Really need basic pinout.

Have another VERY useful one that could save members thousands of dollars. Not sure if anybody here knows what a "Bigmap" ECU mod is, but is is basically a custom firmware that will allow for ECULoad values over 100% (Aka factory boost) - Recently the guys over at Club3g have managed to modify an Eclipse 3G ROM to include load up to 200%).

What this means for us, is if I can match pinouts and add a pin for knock sensor we can gain the following from a factory magna ECU by loading on the custom rom:

- Octane based tuning
- CEL on Knock
- Provision for Boost up to 14psi
- Ability to retain factory immob
- Accell Enrichment

If anyone has any of this information that Dean is looking for it is in their best interest to hand it over so that Dean can do some research/development with it. Im sure he will be more than happy to share his findings with all of us (the magna community) so that we can better mod our cars.

Cheers Luke

Life , what is the part number of the ECU you need pinouts for? i have one at home for a grey import 6G72 delica , and another for a US spec Montero Sport ( challenger ) 6G72

You can change the map axes in the existing ROMs with ECUFlash. You just need to keep in mind that there may be other - as yet unidentified - maps that use the same axis configurations and that changing the axis values may have undesirable side-effects as a result of the changes being applied to the unidentified maps.

Once you find all the maps that use a given collection of axis sets, it is quite easy to retro-fit bigger maps to the Magna ROMs. I've not actually attempted it yet, but I have thought it through and have a pretty fair idea of what's needed. Our ROMs have quite a bit of unused space that can be used to accommodate such things... (unlike some Evo 8 ROMs which have very little unused space).

Oh, one other thing - nearly all the USDM ROMs of interest (including the TJ/TL/TW equivalent Diamante) are set up for 2 oxy sensors (California emissions). I actually have several Diamante and Eclipse ECUs awaiting "reading" and enough time to check out fully...

Hey Andy,

Federal Spec 3G Eclipses only have the one o2.

Club3g had an issue with load limited to 100% in ECU values, I'm assuming our Magna rom will have the same issue (hence the need to use a custom rom instead of extending the axis).

They spent nearly a year in R&D to successfully integrate "bigmaps" into the rom.

Cheers.

I am not going to give the complete diagram here however as a hint, the KF manual in Haynes has the pin outs for most of the ecu on a single page. The later ones will have extras on them of course but the general pin outs are the same, a TF will run with an unlocked TJ ecu if needed

I think I have one hear for the Tj ecu, I used it to wire my piggyback in

As I recall, the earliest Eclipses with the SH2 ECU were MY2001's. Anything earlier than that has an H8 ECU. From what I've been able to find all the USDM Diamantes from 2001 on were Cali spec, but I'd be pleased to be proved wrong. If you can find a 2001 onwards Eclipse ECU that's Fed spec, then yes only 1 O2...

I don't yet believe that there's a load limit (haven't done enough disassembly for that), but there definitely is an issue with the stock MAF max flow map... if you don't doctor that map the ECU will shut down the engine (TT_TJ had this problem with his supercharger setup, amongst others - there's a thread on here about his experiences; heard from him more recently that once the MAF table was doctored, the tuning worked out pretty well).

The bigmaps stuff Tephra developed for the Evos included live mapping (where the maps are actually kept in RAM and can be updated on the fly) - this could well have been a major integration job, if they did all of that. Adding larger maps on their own, on SH2 ECUs anyway, I'm convinced is relatively easy - but you gotta make sure there's no mistakes!

- Accell Enrichment

Missed this earlier - I believe the Magna ROMs have accell enrichment/decel enleanment in some form, but not sure whether it is a simple formula or in maps. It is something I'm actively looking for.

I know you're going to love this one :) http://img10.imageshack.us/img10/5162/unledmrb.png See: bit.1

I knew that the second O2 sensor could be disabled in the Evos, just wanted to flag it as an issue so that you knew it needed covering...

The MAF clipping table looks to be structured similarly to the Max Allowed MAF Frequency table in my defs. The units/scaling I've used come from a Mitsu source and don't match the units used in that def or in the standard Evo defs.

Oh, and there looks to be a problem with that Fuel map too... If that's what it really contains, no thanks!

:P It's an empty map as this is the development rom - there is no live data to ensure idiots don't just try flashing it without altering it.

This interests me. Could there be the option for adding a RPM type switch to enguage a MIVEC function? I might sit down and go through the diagrams for you. And would you expect to repin the ECU plugs to make use of the unused pin slots?

I would be making an adapter harness. I know there is a full pinout somewhere. I have found it before but havnt been able to find again. Will enquire re mivec.

I'm sure there's an idiot somewhere who ignored the statement about the map content!...

Something else you should make sure of if you want to try running this ROM is the operation of the cooling fan(s). I think the Evo 8 actually used a PWM speed controlled fan (ie effectively fully variable via ECU map); don't know what the Eclipse setup is. I did temporarily install a 4 cylinder Galant ECU to try and read the ROM only to have the cooling fan come on with the ignition switch :( Read failed, but I think its actually an M32R ECU (must open it to confirm...) from a recently traversed reference.
