Hi all, UK user here.

I have a UK/JDM spec FQ300 that i am looking for a tephra ROM for. OEM file on the car was a 93660005, i have had a look through old forum posts and have tried a few and tweaked but none seem to work without issue.

At this stage i am not interested in tuning for power, more so looking for a stock ROM to utilise the tephra v7 features on a stock system and when comfortable its running correct, possibly tweaking the ROM.

can anyone help me with a suitable tephra ROM?

Cheers.

 

I had the same ROM and moved to 96260709 (and since then upgrading to DMA). The only issue you'll have that I recall is adjusting thr knock load, adder and multiplier tables as 9626 employs as more effective but overly sensitive knock algorithm.

 

Hi Hyper,

investing some time on making this work again, would you be able to email me to discuss?
