Nistune Forums

I've done both recently. The setup where on different cars but the same engine, same mafs, same injectors, similar turbo's, fuel pumps, one a 240z the other was a 280z. The drawthru took about an hour to tune to 18-19psi. The blowthru took all day and I still wasn't happy with it. I found that at lo...

Nice buy Matt. Are you going to a big turbo, big injectors, big fmic etc etc? I hear nistune is pretty good for tuning that kind of setup.

I was thinking more along the lines of downloading the rom, editing then reflashing. I see blatz now has a cable for consult II, just wondering if you have something available. I have a maxima in the driveway that could use about 350 more hp.

Is nistune anywhere close to being able to view data in obd2 ecu's?

PL wrote:timing. This thing finished up with around 10 degrees extra timing on top of what I usually run! We were getting 5rwkw for each 2 degrees of extra timing. The final figure was with a safety allowance of 3 to 4 degrees.

this why I use methanol injection. can't beat the performance of alcohol.

Have you zero'd out all the warm up, enrichment tables and start the car?

you can log boost pressure, exhaust temp, exhaust back pressure, intake temps...stuff like that is really good to keep track of and can be done with the techedge.

Went out this past weekend for another testntune session.
Best run was a 11.23@123.9mph. Need some safety stuff before I'm allowed to run again.

matt, have you looked into the turbo z31 ecu reporting knock?

As long as the tp scale is just below the calculated tp value you should be good at the low end. The top of the tp scale should be determined by max calc'd tp via dataloging. You don't want to go off scale. Regarding the maf, yes you can install it into a larger pipe and increase it's flow rate. I w...

sounds like you changed the wrong latency. the one referred to as injector latency change should be b8, the other one is called injection latency, that one should have 75 hex or 2340. the injection latency is a starting point and may or may not be your final value, but that is what several tuners ha...

if those are rx 7 550's the latency should around 75 hex; for some reason your latency change is 255, you should leave that as stock; your fuel and timing maps have differing scales, why is that? there are other things that could be changed but the main thing is get your k value and the latency adju...

I've mapped a bunch of stock afm's to over 300hp, it's most likely a kvalue, latency issue.

post a datalog with afr's, and the binfile along with your injector size
