ecu question

dfvadr · 19-10-2005, 09:21 PM

does any-one no if the mx5 turbo runs the same ecu as the sp20

Critter · 19-10-2005, 10:36 PM

I'd be very surprised......

Astro Boy · 19-10-2005, 10:56 PM

I wouldn't be, virtually every GM car runs the exact same delco computer...

twilightprotege · 20-10-2005, 07:34 AM

but it's spazda.

i'd say no, but see if you can get the code on the ecu

As close as the 323 BJ 1.8 is to the 2.0, the ECUs are both different, not even made by the same company? The 1.6 and 1.8 have Mitsubishi ECUs, I don't recall who made the SP20 ecu...

also they're 2 diffent engines aswell, different dissys and electricals...

NO! they are not the same.

dfvadr · 20-10-2005, 09:00 PM

I understand the computing and possibly the body would be different, what i'm lead to believe is that the wiring harness plug would be the same to plug straight into the sp20 computer or vice versa

project.r.racing · 20-10-2005, 09:42 PM

most of the wiring looms are the same, that is correct, if that is the way you are looking to go, Wolf 3D ecu's hard a direct plug-in for the mx5 so if the sp20 and mx5 have the same looms, then you could put a Wolf3D in without cutting any wires
good idea

dfvadr · 21-10-2005, 10:00 PM

well thats the track im going down but not with a wolf3d though

What's ya point??? If your gonna try and tell me an Astra Turbo, a Commdore SS and a Holden Rodeo V6 don't have different engine you got issues....

platypus · 24-10-2005, 07:05 AM

yes - but the delco unit won't recognise the mazda sensors - it requires a new set of sensors to match the delco

i'd be checking out some wiring diagrams - could prolly get a copy from the dealer if you ask them!!!

project.r.racing · 24-10-2005, 07:54 AM

the poit was greg that you can't put a mx5 ecu in a sp20... just about everything is different

oh yeah, the astras don't use a delcos either, since its not a GM company, just a rebadged belgium ****box

Sorry about hijacking the thread but a quick question for you.
The ecu in the 1.8L 2003 323 how much adaptablilty does it have??? For example im fitting quads and have a plenium therefor can still run the stock AFM and all the injectors have the correct resitance and the TPS can be swapped. So will the stock ecu learn to cope with the extra air or will it lean out?

Cosmo Dude · 24-10-2005, 08:33 PM

At the end of the day you need to know 2 things;
1. Are the engines mechanically similar enough to each other?
2. How closely do the plugs (wiring in particular) correspond?
I havn't been bothered to compare either

(i'm going to regret this)

greg is right on this one - astras arn't belgium - ford manufacture in belguim not GM

astras are in fact GM cars - rebadged and re-engineered Opels over to Vauxhalls over to Holden - if you want to know more try checking out www.opelaus.com

rod - just for your own interest the 2.3l mazda 6 has the same sensors as what the 1.6 ZM engine does and the same coil packs - am i showing interest in the workings of the MPS6? hell yes! of course displacement is an issue here

other rod - has something come up or is it just a brain storm?? - if something has come up try it out first!!! it should work if there is enough similarity in the plug up stuff - but the next questions that need to looked at is how similar the tune of the engines will be - as that is what will determine the firing order and the timing of the firing

otherwise it may well be a bit easier to have an aftermarket programmed up on it - i know that may go against some of your other work but it might just be the best in terms of longetivity

simple answer (well question really) - if you want to run quads, why the fark would you want to keep the stock ecu?

platypus · 25-10-2005, 07:49 AM

if you ran quads what hope would you have with the stock afm?

But not for too much longer either... this new daewoo crap is coming over in container loads... I was lucky enough to be at the dealer launch of all the new models down at the Holden Performance driving centre... The viva, the something else, and the tigra...

The viva and the other daewoo thing is just CRAP!!! But, i beleive that tigra is still european sourced, and i was plesently surprised... for what it is, it isn't a bad car, and is actually very refined, both on the road, and on the track...

Cars with real quads don't have ecu's, hey nate!

BTW.. dont take that comment seriously, as i'm currently getting a manifold made up for the charade to suit silver top 4AGE quads too
