Hi Mohamad, post a log on the street and your rom so we can have a look.

I dont know what engine or specs are you running cause with that boost you could have 300hp, on some engines even more. If you have to much boost on the midrange you just need to adjust the WGDC map, you dont have to run let say 70-90% of WGDC you could run from 0 to 100 if you need it for your needs. Post a rom and log file to check it out. Regards,

0.5 spring pressure to 1.5 bar with solenoide sound about right... what turbo are you running in that engine?

what boost is making on just the spring of the WG?

I would sugest going to the dyno and work on your ignition map as there is to many variables to recomend you a specific ignition timing for your engine, the last 4efte engine that I tune on 97 ron pump gas had 25 degrees at one bar and 7.500rpm was a build engine so i dont remember the compresion or the work on the head but has a td04 turbo.

the stock ej25 engines that I had tune, if they have bigger turbo than stock see power right until redline (around 7.000rpm). it should have planty of power with that engine and turbo combo.

if you here what could be detonation is better to drop not a few but a lot of degree lets say 5-7 to be sure that thats the cause or that is what you are hearing. I have found that the same engine in different places like different lambdas (k20A engines), so I would say that play safe like Adamw recomend you and then on the dyno try leaing the fuelmap.

just log the car and see if is close to the AFR target or too way off. I'm guessing is a NA engine so the chances of kill the engine for a little change in the lambda is low, post a log on your new setup and tell us a little bit about what engine are we talking about.

post your rom to see if we found something odd, and a logger cranking aswell. If it had to much fuel to crank thats a easy fix. Regards

The help in the software can help you out with those ones. But there is a guy that post here on the forum another "formula" for the CCL configuration that apparently work very well I havent try it my self. But that's gonna depend if you have one of the big ecu of link, the CCL control you will only found it from the extreme up.

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
