You can figure out the gear-rpm-mph relationships with any of the many online calculators (hint: if they only give you a rear gear option, you can simulate any trans gear by multiplying the trans...

Bruce Bowling wrote a nifty calculator (hence the Google is your friend comment above...it comes up first in a search):

Assuming it's a 4L60 with it's dreaded...

First off, nice curve. Most folks never get one that flat no matter how hard they try. BTW, what happened at 6400? It's smooth as silk up there to there and then a weird little kink with an...

Scan it and watch the TPS value as you floor it from a standstill. ;) Then dig into the torque management settings to make the TPS more closely mimic what your right foot does.

Just two posts after mine, expanded:


My project has been on hold for about 14 months (probably how long since I have fired up my copy of HP Tuners) so I try to at least stay up to date with my...

There is a thread that you probably haven't seen. Reading it more than once will open your eyes if you can hang on (hint: the really good stuff starts at post 27):...

What jumps out at me is the unknown injectors. New doesn't necessarily mean perfect. ;) Before I dove into the harness (which is indeed a likely culplrit), I would make sure those injectors were...

What you are trying to do is the same thing everyone that has ever installed a 24x kit on a Gen1/2 small block has done (same 18436572 firing order). The injector bank reassignment just tells the...

Mike,

That is really fantastic information. If only my 24x LT1 conversion project had been delayed 6 months, this would have saved me a lot of the initial aggravation of trying to get it running...

Uh, what'd I miss? Is there something in the newest beta that I just requested?

Probably because the only Gen I EFI cars all have removable PROM systems that are programmed using tools other than HP Tuners ;) If you are lucky enough to have a Gen 1 car that you recently...

I have nothing to contribute so am VERY interested to see what happens here. :pray:

My intuition also told me that it was jumpy because of the shape of the bore (the evidence is in the first post of this thread), but when I ran the numbers I proved to myself that I was wrong. :doh:...

Welcome patooyee, I am nowhere near a veteran here either, so I always hope that someone with more knowledge comes along to correct me when I am wrong. I am getting a pretty good understanding of...

Honestly, the first one I did any serious work with was from here:

The one I use most right now is a heavily modified version...

It is, good eye :cool: That picture was taken during a mockup of the new stroker engine (which is currently back apart getting a new cam and some head work). The current reality is pretty horrible,...

Haven't there been inline VSS sensors available since the dawn of VSS? Jags that Run probably has everything you need.

Ah, sorry, I misunderstood what you were saying above. You meant to back into the scalar through logging as opposed to calculating it. No problem :D

I think I saw that one, but it only scales up based on a percentage difference between new and old. Until I understood what the number meant last night and how my monoblade is really just an 82mm...

Feel like I am talking to myself here. Hope I give myself the right answers. :crazy:

Based on a quick test, a bit of reading, some calculations and the TBresizing spreadsheet from 69lt1bird's...

You know, I have been just sitting back and watching this conversation unfold since I am green enough to Gen3 tuning that I don't want to try to contribute.

My E85 station is a ways away and...

Actually, yes. Apparently, I was using the wrong .cfg file above and, after searching around, found the real Idle-Airflow.cfg and did the cold start with that. It pushed my Base Running Airflow...

DBW doesn't have an IAC motor ;)

With DBW, you don't exactly control the TPS directly. It is a result of the PCM having commanded the servo to have the throttle blade that far open. There is no IAC, so all of the air needs to go...

Alright, I mucked around for a few days, knocking the lower regions of the Pedal Desired Area tables down 2-3% at a time until it started acting less like a switch and a lot more like a progressive...
