Has anybody out there used the Holley Commander 950 on a spercharger setup or (any setup)? I have the 89 350 w/Miniram and Paxton s/c and do not want to get into burning chips. Is this an easier alternative? Is it a better alternative? Jimmy

The reason I bought it was that I didn't want to go through the hassle of burning chips. I have a similar setup, paxton, miniram, afrs, etc. The only drawback is that you will lose your tcc control since you have an auto. I have a 5spd so that option didn't matter to me. You could always use a stand alone tcc setup like the ones people use when retrofitting a lock up style tranny in an older car.

Tuning wise, it's really a no braiiner. Took about 5 minutes to get it running pretty good and about a week of driving around to fine tune it. If you have someone riding shotgun, it will be a lot easier/faster to tune.

Lane, does it just plug into your ECM or does it replace your ECM? Do yu then plug a laptop into it? Tell me a little bit about how it works. Thanks, Jimmy

Laptop plugs into the ECM via the serial port. You get a nice readout on the screen of everything going on in the computer/engine, and any changes are done in real time (as you type them). Someone riding shotgun (or you riding shotgun with someone else driving your car) should be considered a necessity (soooooooooo much easier). It includes datalogging software, but it has a pretty clumsy interface IMHO.

It is a very nice system. The things I wish it had but doesn't are:

Fuel pressure sensor/readout
Distributorless ignition
Wideband O2 <-- !!!
Better control over the idle air control valve (though what it has is not bad, I just think I could get my large cam to idle better with a couple extra parameters. )

Thanks but I'm selling all this new stuff and putting on a carb. I don't have near enough time or patience. My new Mini-Ram, Edelbrock 58mm, Paxton s/c and the old TPI setup is now FOR SALE. Bargain if you buy it all.

If only I had money for the TB and MiniRam.

jdaniel

1400.00 buys the Mini-ram, rails with AFR, and the 58mm Edelbrock. I'll pay shiping.

FWIW, You can do both, if you want to they are just not bolt on deals. buy an FJO or DIY WB & plug it up & use the Race software & it works. if you want to use DIS or CNP, you can use the FAST eDIST & plug it up.

I say just spend the $900 or so dollars for the Commander 950, drive it around for a week letting it tune itself (its really not that hard), and enjoy the benifits of EFI. You went this far. Cant give up now!!

jdaniel

Back on board. I just ordered the FAST unit from TCI. I'll let you know how it works.

I saw someone on ebay just sold one complete with WB o2 and 91-92 TPI type harness adapter for $1500, how much was yours and did you get a WB O2?

jdaniel

I'ma dealer for TCI so I got it at cost with the 02 sensor.

Can someone direct me to a website that sells the FAST system for our cars, or just tell me how much they usually sell for new. Thanks

jdaniel

Go to www.tciauto.com then scroll down to the bottom of th page and you'll see FAST.

I'm missing something here. With the com.950 you loose you speedo?

CrazyHawaiian

The commander 950 does not support VSS. 90-92 Cars use VSS instead of a cable for the speedo. You might be able to get around this with a converter box and rewiring the VSS straight from the tranny to the guages (skipping the ECM). Not really sure. Call Holley and see what they say.
