I don't know if anyone needs a higher RPM, but my point was, if anyone wanted to follow the PT guide, they wouldn't be able to replicate Jerry's RPM values.
The other problem, which program has the correct max value.

Your best bet is to check over at the HPTuners site. Chris, Keith or Bill will tell you what the code shows. However as we already know, like why VE tuning works on some V6 cars and not on others, it may depend in the OSID as to the max value. Evidently there are over 500 OSID's for the V6 crowd.
In case it was missed, there is a table were you can essentially turn on or off the VE references. Even though we can't see it YETSome of the OSID's have this turned on and some don't...that table should be in the HPTuners next release.

oooo. hadn't heard that... is that just true with the pre 04 or is that still true with the new ones as well?

Already let them know about it. They are looking into it.Your best bet is to check over at the HPTuners site. Chris, Keith or Bill will tell you what the code shows.

I think they are still figuring out exactly how the table works and what cars have it. Even after all these years, there are still magic tables to be found.

I have a question about this statement.Now, on top of this, O2s will be different in a Texas summer versus a Canadian winter. Because of the much colder winter air, I can get away with running a much leaner (lower O2 readings) in the winter than the summer. Taking my car as an example (Supercharged (or turbocharged) cars with an aftermarket cam) I say that 920-935 O2s are good. In the winter, on the same car, I could easily go down to approximately 915-925 without any increase in KR. If you live in a hotter climate, you may need to add 10% to the O2 numbers that I suggest. These are approximate O2 numbers and nothing is set in concrete... your car, tune and KR numbers will ultimately dictate what A/F ratio your car runs best at.
Wouldn't you want to run a little leaner in the summer and richer in the winter as colder air is more dense than warm air.
Cold Air = More Oxygen which = more required fuel (richer)
Hot Air = Less Oxygen which = Less required fuel (leaner)

Thanks for doing this. This is great info and help.
02-07-2008
Indeed it is. Also, for those doing the Wiki, I found the link to an open source tuner for the Subaru's if you are interested. I thought someone was looking for it and it took me a while to get it since the site was off line. But its back now and I literally just got the link yesterday.

I thought the same as you Jae. That's the reason it's so easier to chip a piston on a real cold day in the winter.I have a question about this statement.

As I understood it it was random for now. Perhaps once the table is accessible to everyone, a pattern will emerge.

I've already started a HPT version of this guide and when it is ready, I will release it. I wrote this guide several years ago and since then quite a lot has changed/expanded and what not. I received my HPT early this year, but work and life in general have kept me so busy, I hardly have time for a breath... but it is in the works, and it will be far better than this one, with info specific to the HPT.
Keep your eyes peeled later on this summer/fall for the new later, greater JerryH tuning guide.
In the meantime, if you guys feel like repeating work that I will be doing anyways, feel free to do so.

Just wanted to prove that the skeleton and a lot of the info is already in place. The rest is to come as soon as I have the chance.
Note the all new videos and occaissional tunes sections!

Does this include the wife/gf tune? haha...

Some ideas:
The Friend tune
The parent tune
The G/F tune
The valet tune
The GM mechanic tune
... and more.

I just found this what a great ideaI have held off getting a turner because I have so little knowledge of what to change. Some ideas on what I would be looking for and what to change to get them right

Is there such a thing as an open source tuner for a GP?
Or at least a scan tool?

Scan Tool

Where can I get the OBDII to USB cable cheap?
