Exclamation *READ ME FIRST-- Tuning Docs,VE/MAF, SES Lights, FAQS!!!! + more! *01/31/07*

-This Sticky is a consolidation of useful discussions and Tuning docs that have been brought up over the years. As new information is added I will update the Date in the thread title.

-If there are any topics you wish to discuss or think should be added to this post feel free to post up This sticky should be here to serve the tuning community, so should contain what YOU want to see/discuss

FAQ
If I reset my PCM/Disconnect my Battery/Battery goes dead will I lose my tune?
---Nope... your tune is stored in flash memory... only way to lose it is if you reflash your PCM. It may idle poorly at first while the car is "relearning" how to idle however. This should only last a few minutes.

I have an SES light. Can I disconnect my battery/pull the PCM fuses to reset it, and then pass OBDII Emissions?
---Usually no... once you reset the PCM (wether by removing power or clearning w/a scanner) the PCM sets the readiness codes to "not complete" for the various emissions tests. You need several driving cycles usually (hot and cold starts) before the readiness tests will complete.

What's the best Tuning software for me?
---The best is a personal decision. Here is some info that will help you decide.

Important Part Numbers:
Bosch LSU4.2 Wideband O2 Sensor (sensor only, replacement for bad LSU Sensors): 021-906-262-b

This might help as well. It takes the thread above me and puts it into a spreadsheet format. Determines the Running Airflow Tables

MAF and Running Airflow Tables

Included now in the help file Bill.

The link for "Idle Operation Part 1" in the lower section (not the top one) is broken. Top link works fine.

Thanks so much for putting this together, it's been really helpful.
