TephraMod V7
I just downloaded the evo8 v7 just to see what it looks like. All I have to say is, Holy Crap! Awesome work, so organized, very simplistic, truly awesome. Thank you all for all the hard work and development put forth for this whole project. I can't wait for the 9 rom to be unleashed after seeing that! So excited!
There are a few things which are a bit peculiar that you have to change.
- In Periphery bits F9A there's a mystery bit that you have to change or else the car won't start. My tuning laptop is broken at the moment so I can't look at the exact bit
Compare the periphery bits F9A between 96260009 and 96530706 and make sure the bit that is enabled in 96260009 gets copied across to 96530706
- Leave the Rear O2 periphery bit on, then you'll need to apply the rear o2 heater disable patch, and then you have to turn the rear o2 simulator on under tephramod options. Yes I know the JDM doesn't have a rear o2, but the rom goes spastic if you turn it off (fuel trims don't change)
- You have to turn FCA bit 15 off or the car will throw a CEL about there not being an EGR valve (JDM cars dont have one)
- You may have issues with the immobiliser codes, again I would need to look in my laptop
I did have mine working with some tweaking.- You will probably get mad throttle hang, theres a thread about fixing it
- You will probably need to adjust your low long term fuel trims, mine went really negative, so I had to rescale my MAF in the low Hz range (around 19-75Hz). You could also slightly reduce your latency, as the JDM cars run a higher value
- You will probably need to adjust your decel fuel cut delay tables, or you will go really rich when you liftoff the throttle
- Your cold start will not be as smooth as before, but reasonable
It was a pain to get it running good, but once you do, the extra features are well worth it! 96530706 is also really smooth when cruising around!
PM me if you get stuck!
I like the extra 1/0 naming scheme for SD/MAF. If nothing else it prevents having to totally re-do xml when tuning a basic/normal rom compared to your highly modified rom.

Yep, I had a little incident where trying to help a local out just turned into a huge mess since my 94170015 ROM had so much more defined/renamed compared to the "stock" 94170008xml. After that, I started doing the xmls so I could always have a completely stock xml file for each rom in case I ever had to mess with somebody else's car.
Ok guys, before I finalize on anything here I need someone to look over everything for me.

Just copy/paste the new axis's for the IX into the top map - ensuring the last axis value is 1000000 still

Awesome! thanks
On another note, can the large maps easily be made compatible with Map Tracer - either standalone or EVOScan based versions?

my question is, would it make more sense to go 9055 (JDM VII)???
there should be no compatibility issues evo 7 and 8 are identical engine and drivetrain wise (ACD/AYC)... input anyone??

I've posted up my version of the BIGMAP translator. 3rd post
The only complicated thing is remembering to make the last axis value 1000000 (so when you copy your fuel map in and the rpm axis is shorter make the last value 1000000.
If someone can workout how to fix that I would be happy

Thanks a million, thats the response i am looking for. the immo disable is no prob, and i have run an AUDM rom on my JDM IX, so i dont think that the rear O2 should be an issue...

The JDM roms tend to get neglected by the guys here, because hardly anyone runs them.
By the way, it says you drive an evo ix in your profile, the 96530706 is for evo 8s and possibly 7s. Evo 9 roms are wayyyy different!
