Yes, I'm gathering parts to install a speed density TPI system in a Toyota Landcruiser with a Chevy drivetrain. If you can give examples of good units with increasing price ranges that will be sweet. thanks for your input. I am inquiring about this possibility because I've been informed that it could be hard to burn a good chip for a vehicle with so many mods.

 

Check out the Holley 950 Commander ecm at www.holley.com It sells for aroumd 550.00.
You will also need a wiring harness that sells for around 200.00 to 250.00.

One of the most expensive (and in my opinion the ultimate) is the FelPro SpeedPro unit. These range in price depending on the options that you choose. One of these units with wide band O2 and sequential fuel injection will fun you ~ $2500. Just wanted to give you an idea as to a more 'topend' unit.

The Felpro is one hell of a unit. Real easy to use and just enough features to be effective without overwhelming you with changeable parameters. After taking a look at Tunercat with the TDF for the 90-92 TPI speed/density cars, there's more options with the GM ecm. It does look like it won't be as easy to work with as the Speedpro and doesn't support a wide band O2 sensor, but there is more there to work with.

Anybody have any first hand experience with the new Holley system ?

About time aftermarket setups were talked about on here. Even though this is the prom board.

 

No more so then with a aftermarket ecm.
reversion, is a constant. MAF MAP other then Aplha-N always will be.
Aftermarkets tend to be less detailed so easier to work with.
Finding a spare Speedpro on Sat night can be an adventure......
rather carry a $25 spare gm...
