I'm curious, what made you for got the ECUTEK over an UpRev? Also, what is your exhaust set up now? Do I remember reading that you changed the silencer for short tails too? Just curious to know what exhaust set up you have vs the sound/volume (obviously hard to hear exactly through YouTube). I suspect the first hack for this will be a micro controller to monitor the bus then when the unit checks for a serial the ucontroller sends it a default serial thus bypassing the serial check then you can use it for any ECU since its married to the generated serial.Great video, thanks for sharing. $700 is a lot of coin for what this unit is and I don't mind paying for the research but the excessive restrictions are just that - too restrictive for the price paid. While I don't mind paying $700 to be able to access the data bus with zero effort the fact that they are reading my serial number on my ECU then only allowing that ECU to use the hardware that burns me because I expect for $700 I should be able to hook my hardware up to my friends ECU and clear his CEL or even program his MAP if I want. What ends up happening when you tighten the reigns too tight to make some money is techies get upset and try to find their own hack on the system. I haven't looked into it really but I suspect that it runs off something like a CAN network. That is my issue with this system - you are spending a huge chunk of change for what is basically a EEPROM programer and just reads data off the data bus on your car. I suspect you need to get the "tuner" version in order to do that. It sounds to me like you want the ability to put a new map in the ECU then do another car but keep the updated map in the old car. Can I do this with the UpRev as easliy? That is the difference for me.Īnd I do understand your point stated above, it truely isn't a custom tune, but hopefully better then a conservative canned map. But the main point for me is being able to "marry" one car demo it, "unmarry" sell it and "marry" another. The other thing is that I drive these Z's a demo's and it would be nice to get a little more power in a conservative manner. But from your comments above, this is pretty inconsequential for an NA car, right? i.e., not a reason to hold off and wait for UpRev? I thought you said that you could tweak cam phasing with Cobb. Hmm.I guess I misheard you when we spoke on the phone. I think we are one of the few Nissan based shops that has hands on experience tuning the Cobb AP, which we've done with the GT-R, and also the EvoX. We are ProTuners for both Cobb and UpRev, and have quite a bit of experience with both of them, so if anyone has any questions, feel free to ask. There isn't much more room for refinement there. On the intake side, at WOT, we run from full advance, to full retard by redline. We tune cam phasing on the VQ35's with haltech, and it's easy to see that the OEM mapping got this one pretty right. As a side note, the vast majority of power gains come from fuel and IGNITION timing enhancements, rather than cam phasing and lift contorl. It's important to make the distinction between Camshaft Phasing (also called camshaft timing control), and Camshaft lift control. The VVEL system is very sophisticated, and it's going to be a while before tuners have full understsanding and control over this. I have been reviewing Cobb's technical bulletins and the AP tuning offers everything except for Cam phasing/lift control.
