Here's a list of my mods from my FS section post back in April.

As mentioned before, there were no changes to my Z from December 2014 to June 2015 (except for the EcuTek RaceROM and warmer weather).

FS: 2014 370z Silverstone Grey with mods

Engine
-Stillen headers (Jet hot coat - Ceramic)
-Garage Line mid-pipes
-Z1 HFCs
-Top Speed axle-back
-UpRev ECU tuning (previous) now EcuTeck RaceROM (current)
-Bored throttle bodies by Max Bore
-Upper intake by Z1 Motorsports
-Extrude Hone lower intake
-Stillen underdrive pully
-R2C intake tubes

I'm curious, what tuner doesn't do a pull first thing right when you get there to make sure everything's cool and to have a base line right off the rip? So if you showed up you'd have a dyno for the uprev tune, then he installs ecutek and tunes the car. this would give us a before and after same day, same dyno, same temps etc. I'd be very surprised if a tuner just wiped your ecu without doing a thing and started fresh tuning with ecutek. His style might be different but I've never seen that done before unless for example like me I've shown up and wasn't tuned for a 3-port boost controller or new EWG and going WOT right off the rip would of been pretty dumb. Just my $0.02.

Well Scott my tuner took the best pull my car made with Uprev that didnt mean he just put it on the dyno and wiped the ecu. The dyno chart is to show the gains from switching the software. Thats why whenever i do any changes to my motor i go to the same dyno. Also i will be going back to the same dyno when we switch over to E85.

So you're good to go, he did run it then. You have a before and after and not one from December then.

I dont know if he saved it or not but when im over there changing over to E85 i will ask him.

I can't wait to do it! Plan is it do GTR injectors as they can be had for cheap and a DW65c should be 100% drop in without modding the stock surge tank. At 265lph it's better than the bigger cheaper walbro. I think it's worth it though at $169 vs $80 to not mess that up. I just wanna here 100% if a pump is needed.

Does uprev have a fuel pump duty cycle??

could the red line on the graph be the UpRev pull? The numbers of the red line see to coincide with the numbers on the December 2014 pull pretty closely.

been a few years since i've had a car on a dyno, and am definitely no expert.

Yes the redline is UpRev.

pretty impressive.

this thread and the fact you can correct for gear ratios with the new phase 2 racerom pretty much has me sold on ecutek. only drawback is that there is no end-user control, even if only for the more simple options. (i don't know how to tune anyway though, hahaha)

Thanks Jon we'll be going E85 next week and see what happens. But like we talked about before going into the heads and extrude honing,3 angle valve job with some exhaust cams should open the motor all the way up.

John, I want to see his numbers on my dyno sheet next week!

Might have to copy/paste though lol

Nice thread and nice gains, glad people are starting to show the differences Uprev vs EcuTek

It appears ECUTek is now picking up momentum in the Z crowd, finally. The only thing that would send ECUTek over the top is end user tuning.

Crazy thing about this dyno is that he is making power all the way to redline
