N54 FBO with METH map 3 UK

dance171 · 10-20-2015, 10:13 AM

Hi Guys

As above i have had my car a short while now which has got the mods in my signature

When it first got done the dyno showed 474bhp and 575lbs of torque but the tuner advised this was running low boost as the car kept misfiring. Ive since changed all spark plugs, all coil packs and there has been no misfiring and the car is running very smooth

question is the car is apparently capable of over 500bhp with the mods i have which the tuner has apparently done but its not been proven yet! We are due to go on another dyno day soon and i want to make sure i can get the best figures possible

Whats the best way to set up the JB4 running meth for my mods? I have attached some pictures of how it is set up at the moment should anything be changed?

Cheers

Hi Guys just done some logs in the car from changing the meth additive from 35, 40, 50 and finally up to 60 (the tuner had it on 40)

Can someone that knows what they are looking for tell me which would be the best setting and if there are any other settings i should change? 60 definitely felt like the car pulled the strongest

Attached are all picture logs and all excel logs

Cheers

Well the best way to start would be load up the latest JB4 firmware. It's 31.7 by now I think and yours is 30.2? Read up on it over on N54tech. Be sure to pay attention to the new parameter settings.

Then if you don't already, some sort of backend flash, either BMS or BMS-MHD RACE flash.

After all that run Map 3 as usual and step into meth add with plenty of logging to check.
