I want to tune my B16A T3/T4 54 trim .63ar turbo on C-16 so I can boost 18 psi when I'm on the track
I've got 550cc injectors and I use Crome w/3bar mapsensor and I have a wideband and a EGT guage

My question is how should I tune the ignition tables?
How much should the max ignition timing be when I'm boosting 18 psi?

Thanks.

 

im tuned to 19psi on pump gas and have no detination problems at all.. as for how it was tuned i didnt tune it, it was tuned on a dyno at a shop

 

PSI is relative, depending on turbo size, but if its a t3/t4e, 19psi can be almost pushing it.

yes i know that.. its a presicion sc44 t3/t4 turbo if i had of had the money fore more tuning i would have put in some c16 and saw that the turbo would ahve done after 20psi because of the efficiency of the turbo.. i will go back soon and hopefully hit the 500hp mark on race gas..

 

I would run race gas at that level, but C16 is overkill for only 19 psi.
