Re: How aggressive is the GTiR timing table?
need some work with timing, but I would say its much better now

Re: How aggressive is the GTiR timing table?
my advice is not related with your question, but still: 1. Fix load resolution. You dont need half table with same ignition timing. Better use more resolution on high load. 2. Nissan ecu is not good at fast throttle transition (in terms of ignition timing), so I recommend lowering low load timing, b...

at first set fuelling at WOT 4th gear. After that adjust injection latency to get good idle afr

Re: N62 MAF Mapping
Increase injector latency, decrease K.

Re: Issue out of nowhere: SR20DET bogging above 0.5bar boost
try different boost gauge. I guess you have overboost.

Re: Help diagnosing SR20 engine failure [Tune, Log, Pics]
I did not looked at log, but: 1. it was knocking hard; 2. too much advance in mid range; 3. does your CAS was set in proper position? Checked with strobe light? Because if not, it makes things even worse; 4. never do tuning without external knock detection system, unless you are sure that ecu is pre...

Re: Increasing Boost - the best way to handle TP
in short: rescale K so that at max boost you hit somewhere 100-120. Rescale fuel and ign maps to get more resolution on high load, and lower resoliution on low load, because oem have too much resolution on low load, and vice versa. p.s. fit 350z maf, boost 1-1.2, later change turbo to something like...

Re: S13 CA18Det Fuel cut at 15 psi?!?
i dont see any fuel cut in the log, just lifting throttle.
If you can not reach bigger boost, maybe you have big boost leak. Have you done boost leak test?
Also, maybe you just have spark blowout issue.

Re: Light throttle lean issue when using FP ecu's need help please
for me sounds sort of idle switch issue (even if it says its off). I would try to adjust TPS for higher voltage while its on idle and see if there is any correlation

Re: Lean AFR on certain RPM
if fuel system is modified and especially if fuel damper is removed, 6cyl engines often suffers for lean spots in some places, because of fuel pulsations. Even on this forum was not so old thread about that, so may be its the same issue.

Re: Lean issue Headache. Have tried EVERYTHING
I dont see any reason to be lean except tune. Ok, few things for you to think about: 1. I usually find that for 850-1000cc injectors latency works best in range 800-900. In some cases even around 1100. Never ever lower than 800. 2. Change K value until fuel target table afr values matches real afr o...

Re: Lean issue Headache. Have tried EVERYTHING
looks like you dont have right tuner and this is your problem. Good tuner will not send tunes via email. If he is remote, at least he would connect via remote desktop. Engine from engine very different, especially when we start talking about 1000cc, e85 and other modifications. It needs proper tune ...

Re: Q45 AFM max HP?
how to you calculate 20%? 5.1v compared to 4.8v does not look for me 20% difference. More like 6-7%

Re: Base image S14A vs S15
I would say s15 timing table looks like crap. So maybe they hired cheaper tuner?
