you will have no problem maxing out the VF37 with the stock engine, it can take that turbo no problem with a proper tune.

i think is something around 104... but to be honest doesnt matter as alcohol cool everything they usually performe like higher octane fuels in some occations... you will not be octane limited to tune that car, we have 97ron pump gas here and I have tune 250whp 2.0 B series without problems reaching MBT, as the B series ussually you dont have really high CR as other engines (cause is very difficult to get more without modifien the combustion chamber on the head). 12 or 12.5 is ussually what you get from those engine and with massive cams to make the power you shouldnt run into problems with knock, be aware cause you never know but with methanol you are gonna be fine.

I will keep toluene out of the equation as is not good for the engine in the long run... I have tune many B series engine and you will probably reach MBT with RON 100, as I have reach MBT with 97 RON many times in many high rev 10.000rpm B series engine. methanol is not 135RON, but is a good fuel. You will have good result with that blend, but you will have more power with more methanol cause it has more O.

2.7ms is a good starting point.

it happen to all of us! I remember a couple of engine that give me problem and thas igniter module malfuntion, I prefer to run smart coils

i dont really read plugs I watch to the wideband sensors... but I would say lean...

post your rom to try to see if something is missing

what a fun race... you almost had it! you need 5-10 more hp!!!

I always wanted one of those cars! great engine!

if you ask me I would start with the rom of the plug and play option for the civic, I have use b16 roms on all 90' honda engine and they are always a good starting point, cause is such a simple engine anything would do the job. the Vtec killer with large cams is gonna be a pain in the us to drive on the street, but is gonna sound amazing when the cams match the engine at hight rpm. I would stay under 28° or even 26° at wot before going to the dyno to be safe.

I have never work with that engine before but I'm guessing is like a EVO engine, in that cause we have 97RON fuel here and I have never reach MBT at that pressure with that fuel, I would need a meth/water injection or something else. But the dyno will tell the story, if running less timing make more power be careful cause it could mean you have knock with the old map that have more timing (I dont know if you are running any type of knock sensor on your setup), if it is a stock ecu sometimes I have found that running to much timing make the sensor pickup knock and retard the all ignition map and make the car actually slower that a ignition map with less timing and no knock.

sound like the accel enrichment is off, do the same as with the idle map, save the rom and then have a go with the accel enrichment, you can tune the part that you are taking about pretty much without touching the street or the dyno, and then go for a ride.

you just need to tune your engine, any respetable tuner should do a good job on a NA build like yours. I have tune some BMW engines and if you ask me they normally run from 25-28 of advance at wot with everything tune (good fuel map). The base map is always safe so is normal that a final tune has more timing and normally less fuel aswell. If you are gonna tune the engine I would start with the base map not the one from the rally car. Tune the fuel map and then go to the dyno and tune the timing.

I dont see lambda on your log, is the engine misfire at that rpm? why you brake 2 rocker arms? cause if you dont know why it may happen again

yess check the timing and just to be safe check that you have oil going into the turbo...
