I have an 88 Iroc and am gearing up to purchase all the needed euipment to tune and burn my own chips when I stumbled onto a guy that has Accel Calmap that he wants to sell. I was told it replaces the MAF and you can do real time tuning on the car,, sounds neat but I have never heard of this. Anyone have opinions on this setup? Any and all advise would be very helpfull. Thanks, Larry.

is it a gen 6 or gen 7 accel unit

Good question, one I did not know to ask,,,I will have to ask the fellow that has this setup,,,,he wants to sell it to me,,,I did not know the questions to ask him,,,just wondering if anyone has any experience with it here.
Here is what I know about it so far,,,,,it is for 87-89 cars and replaces the MAF sensor,,,you have to tap into the MAF plug, (2 wires) so I assume you just install a pipe in the air track to replace the MAF,,,this also plugs into the computer and takes place of the stock chip from what I understand,,,you then plug this into your laptop and from there you can do real live tuning while driving, racing or whatever,,,only catch is from what I am told,,,,,this system stays with the car,,,once you tune to your liking then you simply unplug the computer and go with it,,,but the system itself stays with the car and once removed you would have to resort back to the stock chip. This is all I know,,,,I am all set to buy all the stuff I need to do my own tuning and chip burning (thinking of pocket romulator for real time tuning) from Moates when this guy pops up with calmap setup and wants to sell it to me,,,but since I am not a computer guy and just learning how to tune with one,,,,I can't make a wise decision,,,so I am hoping the knowledgable people here can set me on the right path,,,,,,Thanks,,,Larry.

I'm running a Gen 6 DFI with great success. My car runs mid 11's and still passes an emissions test!

Okay,,,,I found out today that this Accel Calmap system is not gen 6 or gen 7,,,,,this is one of the first Accel Calmap systems that came out when these cars were new,,,(late 80's) Not sure if any of the younger folk here would be familiar with it or not.
You can tune on the fly with it,,,using your laptop, and you can change and save anything you want I am told,,,,It replaces the chip in the ECM and stays there, and when you want to make more changes you simply plug in the lap top, you can also monitor all engine functions while driving,,,,sounds like a decent way to go,,,but since this is one of the first systems and is as old as the car I am a little leary about any tech support I might be able to get. The seller told me the only thing missing from the setup is the data cable,,,he told me it is still available from Accel for around $50. Otherwise it's all there. you remove the MAF sensor and install a pipe, and there are 2 wires that splice into the MAF sensor plug,,,,you also have to splice in a MAP sensor somewhere on the intake,,,thats it,,,then you plug in the chip that replaces the e-prom and plug into your laptop and you are ready to tune,,,sounds too easy to me. He no longer has an 87-89 F-body (which is all this will work with) so the system is forsale... So how about it,,,,anyone used this before with good or bad results? Larry.

You may want to give Dan White a call. Do a search or Google for:
Dan White Racing. You may need an interface harness to connect into the factory wire harness.

Will do,,,thanks for the tip,,,maybe he can shed some light on it for me as well,,,,,thanks,,,Larry.

In case you are still looking, I have an Accel Gen 6 & harnesses sitting here in a box for the L98... I pulled it this fall, shortly after dynoing at 400 RWHP on the Livernois motorsports chassis dyno. It's got a good tune for the TPIS Miniram stroker motor.
It ccomes with the CALMAP software as well as a nitrous, 700R4, and cooling fan harness option. I'll be posting it F/S pretty soon.

Yes I am still looking. What are you looking to get out of it? Did you buy it new? Everything there to make it work? You can shoot me an e-mail at hotrodjones@fuse.net
thanks,,,,Larry.

I'd consider the newer versions if you were going to go that route. The support for the older version is non existent except for other users. I ripped out an obsolete 91' version that I couldn't get accell to even admit they made it (no records left in thier system on it) let alone get files for it. The earlier ones like mine only did fuel and used the OEM spark setup. Didn't get along well with my mods above 3k rpm not being able to reprogram it.
Just my little experience with it was a 6 month frustration, you may have better luck if everything comes with it.
Rich at Cruzin' performance may be able to help you find a cable too. He pretty resourceful.

You can have my old Accell box, its just a doorstop now
Actually not even heavy enough to hold the door!

I kinda figured the tech support on something that old would be difficult. One reason I was shying away from it,,,,I don't know alot about computers but knowledgeable enough to know that every six months something new comes out to replace the old,,,and tech support on the older stuff is none existent after a while,,,kinda like home computers too.
Thanks for the heads up. I may get in touch with Moates here soon and just buy a pocket romulator and chip burner, the necessary programs etc....and use my lap top and just experiment and figure things out on my own.
So where is Strongsville, Ohio? I live near Cincinnati,,,,I think you are the first I have seen on here that actually lives in the same state as I do,,,,LOL....Merry Christmas,,,,Larry.

Just south of Cleveland (barely)
Lots of guys here from Ohio, they just don't show it
I'm a pretty big fan of using the GM stuff and going though the learning process.
Lots of things are common between the systems just that the aftermarket stuff is a bit easier to start with. Options for nitrous etc are available on them that we have to do code changes to make happen. I haven't had much experience with the new stuff but know it costs more than I'm willing to pay.Process of tuning is mostly the same. if you don't understand the concepts of what is being changed it can still drive you nuts

Sounds like it's an Accel Power Processor unit. It jumps between the factory ECU and the factory harness. It's basically like the Gen 6 except for the fact that you can not adjust timing. You can adjust the fuel tables though. The idea was good but since it only allowed adjustability of fuel only...it wasn't as flexible as a full Gen 6 unit. Good product for what it is though. Unless of course you have of course you have an adjustable ignition box from MSD, Accel, etc. The idea was good...if only Accel kept up development on it back then...

Hi, I am 16 years old, and recently bought a 1992 Camaro with accel calmap, i think it is gen 6, because the software they gave me is calmap 6.2, (by the way does anybody know how to update it or get a newer version, because it doesnt run on my vista laptop)but my real concern is that the car starts fine and the engine runs perfect for about a minute or 2, then it fails, and starts behaving really weird, sometimes, it even accelerates by itself, or suddenly it turns off, will someone be able to help me program with calmap, something that will give me optimum performance on the camaro, or if someone has a configuration that fits my requierements, or maybe if i uninstall the supercharger someone can give me the parameters i need.
Here bis a list of all that has been installed on the car:
Transmition: T56.
Engine: 400 oversized 0.30.
Supercharger: paxton supercharger SL91 with 2.5´pulley.
7´´ fluidamper
3.5 mapsensor.

32 lbs. injectors with oversized fuel rails.
1000 CFM throttle/Force fuel injection
Performer RPM or Victor Junior intake manifold.
Eagle connecting rod
Venolia Piston ZGS Rings
Part II Heads (ported)
SLP Headers 1" 7/8"
Victor Junior Mufflers
MSD MUltispark/coil/distribuitor GM Original
Final compression: 10 1/2 :1
1.6:1 Rocker
Cam Dynamics Hydraulic Roller
RPM 2500/600
Cam Part # 119531
Deg DVR@ 0.50 INT 222 EXH 286
DEG Lobe Centerline 112
Gross Valve INT .510 EXT .530
Aeromotive 1000 fuel pump and regulator.
Thanks i really appreciate yor help

The DFI Gen 6 works best with older laptops. In order for you to program the DFI, you will need to burn a DOS boot disc. Boot your laptop with this and you should be able OK.

The motor you have is going to take some work. I have a 406 program that can get you in the ballpark but adding the SC changes things. Make sure you have a 2 or 3 bar map sensor otherwise tuning will be difficult. Also, try to get an external wideband 02. You do not want the motor going lean. Keep the AF at least in the mid 12-1's.

Hi, i am really interested in the program you are offering me, and i am willing to uninstall the supercharger, and as much things as necessary, until the car works fine.
Thanks
