Nistune Forums

I have been doing research and as far as i know, u can use the stock springs with poncams 11.5 lift. Any more lift and should use aftermarket springs. I did order the ones from FRsport, cheapest ones i seen around. cams and stoppers $450 shiped to canada, i also got some new rockers coming, head stu...

just wondering what kind of power increase is expected from these vs factory?

well i got the aftermarket FPR as i was eventually going to be running at 4 bar to make my 550s become 660cc i would like some info on what kind of timing to be running at around 0vacum to like 3-5 pounds of boost? mabey i can spool her a bit sooner :) i believe the rear housing is 8cm . I mean its ...

adjust both rev limits to desired amount, u only have 1 set to 8200 and other set to 7k. is your valvetrain stock? i would NOT recomend revving that high if it is. ure Air fuel ratios are all messed up going way to rich most of time Also ure fuel/rpm scale will need adjusting as its only set to 6400...

so i was having some major tuning issues and could not figure them out! would go lean as soon as boost would hit then would go rich, i tried to tune around it with no luck whatsoever. Looking over logs i noticed injectors where open for way to long close to 20 ms , So i decided mabey it was my FPR ,...

This thread is kinda a test on Both the said turbo and the NONAME AFM . Meter was made in USA and is a replacement one So Yesterday fiddled a bit more then heard fuel pump struggling. i Have a aftermarket Adjustable FPR , i poped the hood and holy hell ... vacume line hooked up and over 60psi at idl...

so i bought the said turbo and install on sr20det red i had stock afm and was seeing 5.14v preatty much when the BOOST kicked in long roll on it could somewhat maintain proper afr but during fast shift went lean :( Decided to try a NoName Z32 cause im cheap also bought the apexi super intake kit cuz...

Thanks again for the quick reply I have to go back to work here tomorrow for a week so i wont get to play with what i want to "Theoretical Pulse width (TP) = MAF Lookup * Injector multiplier Injection Pulse width = Fuel table [ RPM , TP/256 ] * TP + Injector Latency + Various enrichment" I...

Ps i think in this run particular never got hotter then 74C
PPS since having this car then installing Nistune i dont think i have ever ever seen it use warm maps just cold map
think it has a 70c thermistat

hey matt thanx for fast reply, its now 12 30 am here so i assume somewhat morning for u. reviewed the log and in closed loop o2 voltage is bouncing around from like .13v (15.6 afr) to .97V (14.2afr), then when it starts to run rich it pegs over to 1.14v (13.5afr) but continues to drop and then bounc...
