Trav, cool toy! This thing will come in real handy for autocross!
Will these still be available in mid to late summer? I'm getting the car painted in the next week or two, so I'm going to be a little short on caaaash for a bit (that and the fact baby needs shoes, also).

The one I have for the Lex does in fact accept programming changes,the thing came with the wires switched around in the plug however,and luckily didn't fry the Lexus ECU! I have a '97 Monte Carlo ECU,have the diagrams from the really big Motor manual as well,maybe I could fax them over sometime,if that'd be easier.

I don't see how it is possible to modify or change the fuel and ignition Maps externally with a add on device. These are already pre-programmed into the 2732 eprom

In order to modify the "maps" externally, we aren't really modifying the map at all, but rather tweaking the signals a slight amount.
For more information, do some searching and read up on the Apexi SAFC, as it is the mainstream equivalent...just pretty, and much larger (and a few bucks more). This is by no means a tunable PROM, but rather a signal-tweaker. Read up, it's pretty interesting stuff: http://www.google.com/search?hl=en&q=apexi+safc

shipped to denmark... uum i'll check on shipping and let ya know.. takes about an hour and a half... (25minutes if you've already done it before) we have Mitchel for all wiring diagrams... from Alfa to Zagonda!
lol... always questioning.. we are tweaking the signal... i'll see if i can't get a MPEG of the tuning screens tonite. and show you what you can change with the unit.. it's pretty in depth.
I think that i have almost every aftermarket add on for my 2.8L (heavily modified). And this is something that i'd be definitely interested in. My nitrous kit is in the mail and on it's way and i'd like something to be able to switch back and forth from racing and street driving.
I'd like to see some #'s. Just how much h.p. and torque are we talking about with this thing. I'm more interested in raising torque levels.
I'll be following this post very closely.

It's ready... we've run my car and Donalds.. for many many miles.. done stupid things and it's easy to fix if you tune too much or too little fuel.. timing etc.. sweet. the new PDF installation manual will be loaded soon. dyno sheets soon to follow.. trying to make it all nice and readable you'll see it's painfully obvious that it works...
Alright my friend has a '90 Mustang 5.0 Auto, with all the K &N, headers, roller rockers..... his car shuts down at 140, will this solve the problem? he cant rev is car in park or else is stalls, we dont know why think this might help it? - or have a clue why it does that?
what else will this help his car out with?
He really wants to fix the stalling when reved in park/nutral - when your floor it in any gear it is fine, doing brakstands, its fine.... when your driving and put it in nutral i belive you can rev it though...
Well let me know by e-mail Physcokyle@aol.com
Thanks Kyle

Oh god, I've got to find a cheapo laptop, like soon.
Trav, one other question. We can use this same software on everycar we have, just install a new box into the wiring harness, right? So how much are the additional box's? It would be cool to set my Dad's expedition up to get 25 mpg in the city!

Travis, i was just thinking that the computer auto adjusts (learns) for each motor and tries to find the best balance for it...
This piggyback unit will certainly mess with the "ideal" state for the computer. Will the computer actually try to combat the inputs that the piggyback unit sends out? Or is it wired in so that the computer is more or less unaware of the changes?
BTW where are those dyno sheets??? hell even give me a hint at the gains...

just a bit over 20hp with timing and fuel.. the fuel made a larger difference then the timing. I'll post em once we're happy with the settings and sure it's BEAT able.. i drive this thing pretty hard everyday and want to make sure it's up to my railing on it.. and then we'll know anyone can use it.
the learning of the factory unit doesnt' change.. the magic box doesn't fight with anything.. just makes it better! a knock sensor yes.. it can read a knock sensor.. but i'm not sre on how it effects the system.. i'll read the booklet and ask Ed and get back to ya.

Mmm... This should be able to fix the rich condition at high RPM of my 3.4. I'm definetly interested in getting one. Put me on the list. I need to see how can I squeeze those $300 under the table without my wife noticing !
Damn! Just when I find all the information about reprogramming OBDII PCMs using the Tech2 and that SPS Flash Kit... something better comes along... actually, you guys posted way before me, so I just suck for not reading all the threads, lol... I WANT ONE!! GIVE IT!!
Allow me to verify something, is this thing going to be able to correct the N* woes of PassKey, ABS and all that other fun stuff, or does it just tune signals at output from the ECM?

It tunes fuel and spark. It does not change anything else.
If the fuel and spark characteristics of the engine are consistent, then this could be used to tune the torque reduced spark out to normal advance and recover the lost power, provided its adjustment ranges are wide enough. So yes, it can work, but not in the way you were thinking.

Nice nice NICE!!! Every time I think I know about Fieros I come on here and you guys blow me out of the water. U make me sick! ;-) I am picking up my old t-top turbocharged 2.5L "duke" from Ed Parks in a week or so and I am planning to build the engine using the 195hp duke info. Except for the CR that is. It has the Holley T/B on it and matching intake (specific for a FIERO) and was wondering can your magic management system tune it for max performance? I dont have a clue if there is a special "chip" in it now or not. I see you are in GA and thats where the car will be heading once restored for a few shows. Could I arrange for you to tune it since I know squat about that kinda stuff?

How "hideable" is this little unit? In the class that I race in, I can reprogram the ECM, but only as long as it fits in the original housing. The only interior piece left from the original car is the dash cover(no guage pod). The ECM is mounted to the firewall where the pass. seat used to be. I'm running the 2.5L, balanced and blueprinted, but otherwise stock. The ignition timing beyond 4200rpm is a problem I've been told. My motor pulls to 5500rpm quite easily, so I'd like to fix that problem if at all possible.

Hoop! Until you get your own laptop, I have one. I've also got the ALDL cable and WinALDL software so we can see what the factory ECM is doing before changing anything.

I'll take all the information you can give me. I need to program an ODB II to think the A/T is there. My email address is in my profile. Thanks in advance.

Free "BUMP" Travis, you mentioned that you removed your MSD box, does that mean the piggyback won't work with MSD? The MSD advertizes hotter spark at higher rpm, does adjusting spark with the piggyback address this? Push come to shove, I guess I could just put in a shift light and stay away from the factory fuel shut-off rev limiter. Boy that sucks when just as you push the clutch in to shift the engine shuts down (computer shuts off injector pulse). Life is just a matter of compromises.

i removed the MSD cause we ok ED wants to squeeze out the MOST with a rather stock ign. set-up. i have a bigger coil but the dist. ICM, Pick-up coil and such are just plain ol' NAPA parts. once he has deemed the car "DONE" then we'll put the MSD back on.. but the MSD 6a and 6al have a big jump at 3500-4200 when the box changed from multi-spark to capacitive discharge. it shows up on a dyno and woun't be a realistic reading for the piggy back only testing.
