Does anyone know what sd rom can be used to replace 90550001

 

the modified 9653XXXX ziad has done seems to work iv not tried it though.

 

Is that a sd rom that has been done John ?

 

u need to fix a lot of things... but a 96533706 will work on the 7s. i think burnsy said that the e7 ecu he had didnt have a wire to add the MAT sensor. so he had to splice into the MAF plug.

i made a thread about convert from 9626 to 9653 look for that... it gives u most of the fixes needed. but the sd rom required a few more.

 

Cossie1 has tried 9653 today but had some issues with it

I am sure he wil post up his findings and see if someone can give any pointers on how to get it running correctly

 

i've used the rom in post 1377 in this post https://www.evolutionm.net/forums/ec...mod-v7-92.html and it seemed alright on the two 7 ecu's it was loaded on to.

As jamie has said, I today messed about with 96531706 (the SD version), and it works ok (ish) on my E6 with E7 ecu.

If I load the rom on, with my fuel and timing maps, the car will run, however it won't idle propperly (stumbles around 650rpm and will cut out if left), however when driving it will throw a cel saying that the intake temp isn't reading correct (or words to that effect), so I had to edit the rom to make it think it's using the fuel temp sensor (as per usdm cars), then it runs ok (still won't idle).

However it stutters around 2000 - 2500rpm, therefore I tried stutter fix1, this initally cured the stutter however it was short lived as a few miles down the road, I had a cel logged.

Turns out stutter fix 1 causes it to throw a P0125 (too long to access closed loop control), however when it throws this cel, it will atleast try to idle.

So I changed to stutter fix 2, again it won't idle, and there is still a minor stutter around 2000 - 2500 rpm, but again after a few miles it throws a cel, this time it says road speed sensor but again it will try to idle once it's thrown a cel.

So I changed to stutter fix 3, this time it stutters just the same as with no stutter fix enabled, but it reverts to throwing the P0125 cel.

So for the time being i've gone back to 90550001 SD and have to putup with the stutter for a bit longer (for some reason the car feels more agressive on this rom, than it does with 9653 v7 sd).

 

jamie there isnt one , that will work correctly .
