Smooth Throttle for UpRev

DIGItonium

Hmm that's pretty interesting. Good to know. I definitely need to get out of this canned tune O_o. We shall see if I still have this car within the next year or so.

Unrelated. I notice there are times I have issues starting the car, and it doesn't matter how hot it is outside. When it starts I smell a bit of fuel as if the engine was flooded.

Starting the car to me has been the hardest part(tuning for 516rwhp was easy in comparison)
There really has to be a fine balance between not enough fuel to too much fuel.
Do you have test pipes?

No test pipes. F.I. HFC and 12" TDX exhaust still. I remember reading about startup issues due to leaky injectors. [shrugs] It comes and goes. There were times I had this issue once or twice a day, then it goes away for several weeks.

Wow you're making nice power. I think 500 whp is my target as well with this new setup, but I care more about quicker and smoother response.

Over 23k miles (knock on wood). The car was with Baker Tuning for over 2 months, and I picked it up during Labor Day weekend last year. Sam says he wasn't given the datalogs so he could send the correct tune, so it was still running the canned tune. So I recorded my logs and sent it to him and heard no response from either Sam or Mike. I wonder if it's because of the MBC that they don't want to touch my car. At Baker, they were playing it safe at 6 PSI (no boost controller or wastegate tweaks) and this canned tune not knowing what my driving habits were.

Nearest tuner for me is in KC, which is 3 hours away. I wouldn't mind having Z1 tune it after the new upgrades. [sigh]

When I took my other car apart I saw several injectors leaking however I fixed it when I put the kit on my Nismo so starting was alott easier to dial in, I didn't think about that until you said it.

When you fixed it, did you use the same GTM-supplied injectors or go with something else? How about switching to Injector Dynamics down the road?

Sorry for going OT, but who knows since we're on the topic about fuel delivery and throttle response. [shrugs]

No I just reversed the order on how the injectors are installed,when I put them in my Nismo I put the injector in the intake first then put the fuel rail on top bolted it down connected the battery and turned the key on to look for leaks.

I'm not sure if this helps with the basics on the VVEL motors.

I guess my question after seeing this is what does Nissan mean by "high Torque" cause I dont think the 370 has "high torque" at all.

I guess that puts you in the Wichita area? Or somewhere way out west?

I would say you might as well make a road trip to Austin and have Jared @ Uprev tune it. Prolly what I would do.

Yup, Wichita. I'll definitely get a tune once the upgrades are done. No one in the DFW area? My friends and I frequent that area [for food].

Too bad a software switch can't be wired to turn off ETC (like VDC button). Haha, this car definitely needs an R-mode lol.

There are some okay tuners here. T1 in Rowlet would probably be good enough. I just know the process they follow @ Uprev in Austin is very methodical and they hold on to all the data for safe-keeping, should you need updates in the future.
