When you use the resize injector function make sure the "change crank tables" box is UNticked and try starting her up, see if that helps.

. Whats wierd is if I go back to 720 it runs super lean at idle now and didn't before. It would run slightly lean before at idle. I'm addicted to this tuning stuff I guess. I can never leave it alone. LTFT and STFT maybe why What is LTFT and STFT? :?: I had the same issue with my engine wanting to ...

good to hear you are sorting through it. what was the original 'k-constant' 39000? was the base fuel pressure checked with tps 'off' eg.1200rpm? seems like a massive drop in k-contant value unless I'm looking at the wrong binary. (which is always possible) My original K Constant with the stock (92 ...

Interesting... I thought at first it was one size fits all for the injector latency (example nismo 740cc = 66ms for all :roll: ) but I am now seeing that you have to find your own sweet spot. Took me (4) days to get start up, idle, cruise & wot but i finally got mine feeling like stock injectors...

For the hard starts it seems as tho its cuz i allowed nistune to adjust the cranking tables (cold enrichment, crank enrichment offset, etc). I added back 4 values at the 158*F mark in the crank enrich and crank enrich offset (that was the car's water temp at the time) and it cranked on the first swi...

Hey guys Have been going thru the run down with installing nismo 740cc injectors. I've found the latency that best for me to be 850 in nistune. Prior I was told 660 but that had the idle very unstable. So I am just asking those who have dealt with experience or installed these injectors what latency...

Ok so I started with a fresh base map (redtop sr), input the resize injectors, dropped the ttpmin two (2) values across the board, put in 800 for inj latency, fpr at 3bars (43.5psi) then I swung the key and didnot start :( . So then I increased the k constant in small increments until it hard starte...

The TPS is set to .40 and timing is 15*. Whats hard for me to understand is that when I run the stock (sr20det redtop) map (370cc inj setting with the 740s in) it starts easy only thing is it has the pig rich afr (naturally). Now after I do the change injector process in Nistune the engine just goes...

Hi guys I recently installed nismo 740cc injectors, aeromotive stealth 340 lph, and N62 (Z32) Maf. After installation and the auto re calibrations (TP Scale, TTP) and adjusting inj latency to 660 the car would give a hard cold start with mild erratic idle (also I recently installed Tomei 260 cams pr...

I thought I was gonna loose some low end power but it feels just as strong as the stock cams down low (according to the butt dyno).

SUCCESS!!!!!!!!!!!!!!. The AAC was at 66%, I manually open the IACV adjuster screw until it went down to 50% +/- 1. Went for a test drive and now no more stalling no matter how low or hi an rpm I switch into neutral. Thanks big time PL, ur a life saver :mrgreen: . cams feel amazing and I am only run...

Yeh I have the stock recirculation valve. Its only since I reinstalled the head with the 260's the stalling began happening. I'll try the IACV tonight and see if that fixes the stalling so I am thinking its related.

On average would these cams go better with more timing tho, more or less fueling?

Nice. I used the latest version for the first time today and was wondering what red/pink colors were (actually thought it was something wrong). Thanks for the color code.

Got Tomei 260* with 12mm lift installed on my redtop sr20det along with a 3 angle valve job and I am looking for some tuning tips to get the best low/cruising power possible and a general direction for fuel and ign wise on whether to + or - values now that I have made the change from stock cams to 2...
