Thanks very much! Too much timing at WOT you think? I see the previous tuner added about 4-5 degrees. Is that based on your experience, or does...

Control packs are set up for a return style fuel system, you'll need to look into the way it's wired, but it won't use the stock FPDM. You would also...

Yep. Ive disabled it quite a few times with no ill effects.

I wanted to let everyone know that the problem is fixed. I want to thank "engineermike" for looking at my data and discussing some options. It turns...

I don't believe that the last few HP from a larger/ported non-stock TB is worth the headaches that come with them in terms of torque control. - ...

I have deleted ISS on a absolute ton of applications and never had a bad result.

Hello. I would be very grateful if you could help me with that information, please. I'm trying to unlock an E90 and need the pinout diagram. Thank...

not that I have been able to find. I have been playing the game of unhooking the vvts when in heat races and then hook them up in the feature race....

Good advice.. it's what I do. The LSA CTSV and ZL1 default to pattern B.. So its good to stay on top of what is being used by logging that channel.

Are there not any VVT enable/disable parameters? And/or zero out any cam timing tables so that the ECU always commands home position.

well you have to do more than just set the idle & drive to 1200 rpm and set the PE to 12.3 and turn off the MDS. you have to dial in your air flow...

I know this is an old thread just wanted to add some input in case other people come across it. If you guys are unsure of what pattern you are in?use...

so I am trying something. I have taken the VVT apart and took out the spring and have engaged the vvt with JBWELD. popped them back together and...

What is the overall diameter of your rear tire? (Use a tape measure)

The timing is low at decent but not WOT loads. compare to a stock file and you'll see what I mean. Mind the MAX VE table in the dynamic section....

Take a video of your wideband gauge face and the the scanner while logging. pause the video in a few spots. Make sure the two match. Also, I...

Put your transient stuff back to stock. You shouldn't be modifying that. Also put your MBT max spark table back to stock.

Looks too lean to me. (lean sneeze?) Have you put a fuel psi gauge on it and verified correct PSI? On the two logs you have the WBO2 logging, it's...

Easy tune for any remote tuner. Most can do it without a wideband if they have the experience but it is still HIGHLY recommended to get the most out...

What is "PT relay" (Powertrain?), and is it something I can check via voltage or resistence checks? The MAF is OK but I can check the connection. I...

Ok, I will definitely double check the ground connections. Thank you again!!!!

1. MAF frequency instantly going to zero while engine speed is still above zero. That can happen only when MAF fails or its power is lost. 2....

Does anybody have a standard .hpt file for an LS9 (corvette or commodore)?
