Help: Pedal, Exelleration Slow Response

[givemeadollar]

I would love to do my own tuning especially related to the transmission. I assume my only option would be HP Tuners. In my younger days of Kart racing then Roadbike racing, I loved test, analyse and tuning. But those were the good old days or carbs. That last Bike was tuned with Powercommander that coincidently tuned buy he same method of the Pedalmax stuff. It would see the fuel pulse from the computer and then add or subtract to change fuel ratio. We would need to tap into the fuel injector harness. I do realize a stock N/A car has very little outright power gain from a tune. And oddly my preloaded 93 SCT tune seems to be about the best.

I 100% agree that WOT tuning is really so irrelevant but at the same time its the only thing that has a controlled test. I actually almost never, other then testing, go wot. I'm all about the whole driving experience. I am sure that PBD just pulled a tune out of a library and sent it which I guess is pretty fine since I have no mods other then 18 airbox. I asked PBD if they will adjust my trans to my liking if I went with them. They said yes but with the countless hours into this tune I should be good. Well it was fun for about 5 min then it was untolerable. Awesome to go down the strip but wincing shifts on the street. They did adjust better but still not great. I now have asked for stock parameters for the trans.

I have not counted out I will try a truck manifold one day and VMP was the only place that agreed to help tune that in. Then PBD because everyone raves so much. But I do which I would have given Ortiz a shot. And maybe I will soon too. I like to here he will help get me to the driving experience I am after. But after this past experience, I would have been better off to go with SCT preloaded tune, adjust shift pressures and then adjust the throttle with a Sprint booster or the pedalmax was nice with the control knob. Turn it up for Drive mode and down for Sport mode to my liking or when my daughter or wife would drive it.

One issue with the preloaded tunes and any tune coming from a big name brand is that they will most likely be locked so you will not be able to make any changes even with your own personal MPVI2 + VCM suite.

Show me a 7 or even 8 second car that needs a pedal commander.... I'll give you a hint, there aren't any since no one that is fast is interested in that ricer shit.

Well of course no one that is just racing in a drag race WOT the whole time would waste there money on something that would not be effective. But even in roadracing and Motocross there are 1/4 turn throttles and such to help adjust to the response you are looking for.

Also we only did dyno tuning so at WOT the car is phenomenal but we didn't bother with around town driving because its not race car shit.

This is what the pedalmax is for, the around town experience. And for me its to level out the feel of multiple cars I own. In Drive mode my mustang GT feels like the slowest car I own including SUV's. Until I start pushing the pedal farther to get the same pep. I turned up the knob and it was more effortless to pass and such. Otherwise I find I push a little to downshift and pass but not enough, then push again.

Yeah, I do assume I would need to start over with a tune. But in all honesty, I've looked at the spark, AFR and such compared to stock in the datalogs and there is not much changed. A little richer up top and the spark is a little less. But my acceleration tests netted the same speed. So I wouldn't be looking to change a lot of engine parameters, just mostly the transmission parameters. And throttle response of course.

I certainly don't know how to go from an oem ford file to a fine tuned race file. That is why I have Ortiz Performance to do the tuning. I know enough to do some of the smaller changes and revisions.

I have never run a pedal commander in any of my personal cars since I get them tuned correctly, so I have no need for a bandaid.

You keep on with your ricer pedal commander and stay in the slow lane, don't worry about my manual whippled car that would walk the floor with your pedal commanded automatic...

As I said show me a 7 or 8 second car that needs a pedal commander. You can't because there is not a properly fast car out there that uses that garbage...

Get your buddy Richard Rawlings to put a pedal commander on any of his cars.
