i let it start for 10 mins under the defogger to let is learn ......it wouldnt learn... NO NTLS no launch control, I liteally copied each n everything into it... each n everything...funny the other features are workin perfectly....and the internal ecu ID is 93660005....... when will we JDMz have sum patch workin....

 

Anyone have any luck with a V5 with all working features yet on a JDM 8?

 

Hello

I've got up to the exact same point you're at! My car is a 03 UK FQ-300. Original ROM ID 93660005. RC Developments told me UK FQ's begin life as JDM GSR's then have the HKS kit fitted after SVA......

I too have no NLTS, strange low idle revs and missing launch control, everything else works okay. I do think the ECU seems to learn as slowly idle has risen to about 750rpm.

I can only get my car to start with the immob. disabled, and you seem to start in the 'valet trap' after the first ECU write - but thats resolvable

Have either of you managed to get any further? Or tried 90550001?

I'm seriously considering getting the socket set out and removing EGR (I've done it on a previous FQ300 without issues or CEL with RC Developments advice)

Reference the clutch switch, how about ordering the OEM part and fitting a second switch? Do we think it's possible?

Rear O2, it is a bit more awkward but not unrealistic to put a resistor into the loom to eradicate the CEL. I will happily modify and work on my loom to move this one forward

 

I think we JDM owners need to club together and make Tephra an offer he can't refuse to patch the 93660005 rom, or perhaps even better the Ralliart rom for the JDM 8.

 

I will without hesitation buy into that

I don't think it's possible to thank Tephra enough for the effort he's put in for others......

I will gladly log/test anything needed, and as said before I'm comfortable modifying looms and adding sensors if that's an option. I'm beside myself with anticipation

 

Ok, well let me put up a post on the MLR and we'll see if we can get a few more people interested.

If so, then I think we should be able to get enough together to make it very attractive for Tephra to do it.

Are you on the MLR, by the way, and if so, what's your username?

 

Have said hello and replied

 

dosh waiting

 

I need the 97250001 def file ASAP!

Please attach it here or send it to gfmileo@gmail.com

Thanks!

 

Any updates if anyone has got a tephra moded rom version working?

Jellyhead i see in your sig your now using 90550001 v5.1 ; is it working 100%?

 

I have an 04 JDM Evo 8 with ROM ID 93660005.

I've just tried 90550001 on my car. The car starts but seems to have a bit of problem. when I tired to accelerate, the car will stall. I think I might have errorneously copied the old MAF Scaling value over to the new ROM, which reads in Hz now. I think this is screwing up the readings.

I've adjusted the ROM but will try tomorrow as it's too late now.

Any Brother have better luck here?

 

I have an 03 JDM 8 and I tried 0001 but some of the features didnt work.

I tried 0009 and it works fine (have to disable immob through periphery) and everything works except the NLTS because mine doesnt have a 2nd clutch switch.

However Alt maps, valley, etc all work fine without any driving problems.

 

So, all Evo 8 does have the 2nd clutch switch?

Is that the main reason why NLTS doesn't work? Any work around for this?

 

Some guys are installing a 2nd clutch switch which will obviously work but if u look up under the dash at the clutch I have a gold coloured bolt that the clutch rests up against and I believe thats where the missing switch should go

 

Thank man. will check it out. Learning new things everyday.
