Important: With any rom change... be sure to copy over your ECU Immobilizer code from your old rom OR deactivate it completely on the new rom (all done with ECU Flash). If your car doesn't start after you load up the new rom, this is why.

Anyone have experience with using a JDM MIVEC or otherwise modded map with 91 octane? Seems most people talking about modded MIVEC maps are on 93.
I'm on a stock tune with most boltons (TBE, LICP, intake, o2 housing), and trying to learn to tune and wondering if JDM mivec map might be too aggressive. I've been logging (with a wideband) so I know I can gradually increase the values myself and observer for knock, but I'm curious what other people's experiences might have been?

i think youll be fine, you my just need to adjust some other things after. Its been a long time sinc eive messed with mivec, but i seem to recall doing a half jdm/half usdm map and it made a huge difference in around town manners...although no its basically a race car only so it doesnt matter anymore lol.

I've read through this thread a few times and I've searched around but couldn't find an answer. Maybe I'm using the wrong keywords or something.
Is there a general consensus on which tables should be tuned before others?
From what I've gathered, with 91 octane at least, the priority should be:
1)Adjust timing to eliminate knock
2) Find areas where timing can be improved, and advance the timing without introducing knock
3)Tune Mivec to JDM map or otherwise
4)Finally tune AFR maps to ~11.5 tapering to 10.9 towards redline
All while ensuring we're not introducing new occurrences of knock
Is this the right approach?
