LS tuning help!
Anyone on the board good with HP tuners that might be willing to help me out with a verylikely simple problem? I switched my MAF sensor and need it rescaled. Ive got HP tuners but am totally new to it and dont want to mess it up!

Re: LS tuning help!
I recommend having a moderator move your thread to the LS swap section of the board. Just send one a PM. Moderators are listed at the bottom of the section pages.

Re: LS tuning help!
What ECU are you using. The factory computer does have some learning ability. It is possible some various driving styles will get it working better. HP tuners is a great tool but difficult to learn. Do very small changes and only 1 at a time.

Re: LS tuning help!
pretty sure your going to need a wideband to tune it.. I came across the same issue when i did the L83 swap in my 87 silverado using the air raid MAF adapter... ran weird, long term fuel trims went way lean or way rich... been a few years. Idled supppppper low, exhaust sounded different. Watched a guy on youtube how to maf tune l83 and poof fixed it. I used a 14point7 wideband sensor adapter + used wideband sensor, calibrated wideband per instructions and runs great.

Re: LS tuning help!
Yes, Absolutly must have a wide band sensor if you are using HP Tune. AEM is your best solution. The gauge has provision to provide data to the HP Tuner Adaptor. I also find the sensor and gauge very useful in tuning a carborator. Made selecting the correct jet and rod a 15 minute job and I now have excellent A/F ratio.
