Tephra what about 8840016/17? I have tested v5.5 (+ accurate boost control mod) and had strange fuel-cuts from 4k rpm up. If you have any good looking version I can manage to test it.

 

ummmmm the fuel cuts from 4k where because someone was using a bad acceleration table.. cant remember exactly..

i will be doing a 88840017 5.10 once I think its all ok

 

Hi Tephra, the original ROM ID was 93660005. I was upgrading to 96530006. For the sheer hell (and in an attempt to understand the 'interchangabbility' of software) I experimented with 91470015....

 

and going to 96530006?

what maps did you copy across?

what idle problems?

 

I copied everything across. The first time, after disabling the immobiliser (0x56d0) and escaping the Valet mode, the car ran fine, I've never managed to get NLTS work.. but I then copied Ralliart maps into alternate and began playing with boost controll, all behaved well - but the CEL was permanently on.

To be honest, since then I've tinckered with so much I think I should start from scratch. Beginning to doubt myself.......

Should 96530006 work in every way on my car? Am I right in thinking there are known issues? Why does completely disabling the immobiliser need to be done?

 

the immob is the only real issue i am aware of.

what was the code associated with the CEL?

 

Codes.....

P0000 Unknown
P0090 Unknown
P0243 Turbo Wastegate Solenoid A Malfunction
P0403 EGR Circuit Malfunction
P0505 Idle Control System Malfunction

 

ok 505 you can fix by adjusting your BISS... There is a thread on it by me - fix is on the last page or so...

EGR - does you car have EGR? if not maybe disable it using the FAA bits... not sure which one but search and ye shall find - otherwise post up a new thread

243 - hrmm how are you controlling boost atm?

not sure on the other 2... weird...

maybe wait for 90550001 as that will probably be a better match to your car...

 

90550001 is an evo 7 rom, and he has an evo 8 fq (jdm / uk spec).

 

hey cossie when do you think you'll be done with the 90550001 ROM. im eagerly awaiting the patch!!

 

when he wakes up

it didn't work first go - but ive sent him a change and hopefully it will work now

once he confirms I will roll in the 5.10 changes (he is running 5.9) and then put it up

 

Tephra. Would you patch 96530006 with Tephra V5.8 (or later), please?!
I can send you the .bin and .xml

 

Firstly, thanks again chaps - I really appreciate the help

Yes, my car (which I was lead to believe is JDM GSR spec?!) has EGR and ICS. Factory boost control is a single solenoid.

I'm happy to disable (and remove) the EGR system - can't see how it's needed will search on the FAA bits.....

243 - Boost is being controlled by the factory solenoid. It's all standard at the moment - no mods to the "pills". I will ultimately be installing an AVC-R.

Am happy to wait and/or test 90550001......

 

hrmm maybe a corrupted rom then..

first time ive heard of codes being throw on my rom's...

maybe try reloading the rom from scratch...

 

Mmmm.... so you would expect this to work without CEL then? I take it disabling the immobiliser doesn't cause a CEL....

If you think it's worth a try, I will start from scratch....

EDIT : I will start from scratch!
