MegaSquirt PNP for Miatas

[rockytenney]

Remove stock ecu and bracket, plug in your new DIYAutoTune Megasquirt PNP MM9093 , bolt it down, run Map line to intake, pull ST SGN 10 amp fuse, start car, goose it a couple of times, hit the kill switch, eat sandwich while looking at the car, congratulate yourself on how clever you are generally, and specifically in this case, how you exceeded your own cleverness expectations. All this for the price of a set of go to the race tires. Of course, an interface in the form of a laptop (cable included) and a dyno (not included) would be required to further optimize for your engine.
The dyno sheets as posted by Jerry indicate that the device as configured by DIYAutoTune does improve torque and hp across the range significantly. The air/fuel ratio is controlled by the unit and the AFM could be tossed for more gain. Someone may notice this missing in SCCA impound.
Jerry and the folks at DIYAutoTune have an impressive product line and development facility, and are definitely focused on customer service.

Joe -

I have little doubt that getting the car to run on the MS PNP is easy as can be. Do you do any of the tuning yourself? The dyno I will take the car to is not familiar with Megatune, and I want to be able to tune the car myself at the track, so it's something I really need to learn.

i think those are pretty good gains considering you had an already tuned AFM. was that an AFM you had tuned at the dyno before? was it an ART? i won't be running a 1.6, but i know someone who is and is considering a MS PNP. i'll be in a 96.

Travis,
I was the watcher and not the doer. I am confident that if I had read the manual I could have muddled through. Populating tables is a repetitive function that is easily handled and you would be working from an existing baseline specific to your 1800 as opposed to a cold start. The displays are great and the menus are more intuitive than your basic cell phone. I am sure the folks there will be able to deal with the various install and tuning problems the user gets himself into. The manual and install procs are on the web site. You will need a wideband sensor to tinker at the track.
Mac Spikes has an 1800 and is going to see Jerry on his way to the ARRC. He would probably let you know how he made out with his "supa fly tune".
The AFM was tuned by John Williams with that engine on a dyno. I am pretty certain that he got all he could get using an AFM.

I ain't tellin him nothin!
I am pissed Joe was whooping my butt at the June race without a Megasquirt! Now I won't even be on the same lap.
Jerry if you see this I need the Curtis Mayfield approved SUPER SUPA FLY tune!

Joe , Don't worry about Travis he is just gathering ALL the info before he breaks open the tin cans in the backyard. They are Silver Certificates given to him on his 1st birthday. Oh and he also has the first nickel he ever saw. To say he will be spending wisely on this project might be a fact. Now me I buy two of everything cause I either break it or forget where I put it.

On a serious note how do I get to Jerry's place, from either downtown or RAtlanta?

[rockytenney]

I am with you Mac. I have discovered that Travis spelled backward is Sivart which according to Wiki is "he with no conscience who makes rational comparative decisions before leaping to silly endeavor". On another note, this type of individual will surely stagnate the economy while you and I will have have two of everything.
As far as that race, I remember that you insisted on taking Road Atlanta turns 6 and 7, the bypass at turn 5 to the back straight is the most excellent route.

The directions to DIY going north from downtown on I85 (in Georgia, an out parcel of Texas) to
Exit 109, left west on Old Peachtree Road.
Right on Satellite Blvd 1/2 mile maybe.
Left on Mcginnis Ferry Road (do not be taken in by the Burnette sign to the right).
Left on Burnette Road (small road just before Buford Highway up ahead).
Left on Burnette Park Drive.
Right into 3690 bldg. Suwanee, Ga. 30024.
The track is exit 129, I would use these going south also.

Have a good trip and do not destroy any relationship we think we have with Jerry.
