Forged Performance: Our First 370Z Custom ECU Flash
 

UpRev has finalized all the ROM's for the 370Z so on Saturday we dyno tuned our first 370Z. Prior to the tune, we installed Stillen Hi Flow cats, and a Stillen cold air intake.

One of the key features of the UpRev software, as the ability to conduct real time tuning, and allows for very precise adjustments to be made quickly in real-time. I ended with a net 15whp gain once the dyno tune was completed.

As a reminder, our Dyno Dynamics dyno typically reads about 10% lower than a dynojet. For instance a bone stock 370Z registers about 250-255whp. Let me know if you have any question.

I was hoping for more. But I am not too fimilar with ECU tunes; is 15whp after bolt-ons pretty normal. And these other companies that advertise 30% increase including the bolt-on numbers with tune vs. the base dyno to pad their numbers?

Thanks

thats more than I expected actually. Im interested to see if there is any change in power delivery and if the rev limter has been moved up. Data seems to end at 7500 RPM. Looks like power is gained all throughout the rev range as well.

I think this was showing after mods, then after mods + ecu-mod.

15whp isn't a bad gain after that...

A true NO BS gain of 15whp from ECU tuning alone is very respectable. We always choose the highest pre and highest post tune runs. We could pad the numbers we choosing our lowest pre tune, and highest post tune numbers, but we've never done that. Aside from the absolute power gain, you also end up with a engine that is running at it's peak from a safety and power standpoint.

I have seen some cars with bolt on mods, running 14:1 AFR's at WOT without tuning which is definatley not safe. Every car is a little bit different, so the level of gains will depend on the current state of the base tune. For instance, if a 370Z came in with an overly rich tune, or overly lean, the gains could be 20whp+ once we are doing properly calibrating the ECU.

As a general rule, we usually see about 10-15whp from normally aspirated ECU tuning.

:iagree:...Nice work!

and you didn't mention this to me when I was just there??????

Sharif,

When an owner comes in and wants to get a dyno tune I assume he buys an Osiris Flash service ($300) and then dyno time. How many runs did it take to get the 15 hp?
Thanks

Because you didn't make an appointment...LOL....just kidding!!! :) :happydance:

Thanks for the insight Sharif.

Very nice. Similar gains to this are right within expectations of a proper dyno-tune. :tup:

Good question - also would like to know

All set for Sharif to tune my car on Wednesday. :tup:

nice! can't wait to get mine done now. not to make this another cobb vs uprev war, but which one do u prefer?

15hp on a reflashed ECU is solid. That's about what I have on my Hondata reflash. What's the torque increase at? The curve is looking great already.

The real question is the price. I paid ~$500 for my reflash, to unlock an ECU for dynamic tuning you are looking at $1000+.

Good work! I will definitely get intakes and probably the hi-flow cats too
