looking for a good run down of all the spec's. i don't seem to find much info on the details and differences between the lt8 and lt12. can some one point me in the right direction. or do i need to call br7 with the group buy.... ?'s are like can you data log with lt8 and how or do i need the lt12. what makes the lt12 better besides being able to run V12/20B. also another thing is can i disconnect the ecu from my car and set it uyp for a V8 and go back and forth just with a diff set of maps. or is the software diff also... my machinist wants to play with some engines on the engine dyno. he builds big drag motors.....possible or what.......

10sec rx7

basically the LT8 has 4 injector drivers capable of running 16 injectors, and 4 ignation ouputs capable of running a V8 in waste spark. the LT12 has 6 injector drivers running up to 24 injectors and 6 ignation drivers for a V12.

The LT8 can only datalog to the laptop where the 12 can be setup to data log to the box, this also includes wide band 02,

with the swapping back and forth the main issue is the ignation pickups, if the v8 has the same pickup there shouldnt be a problem, most of the time i would use a ecu that runs in group fire with a dizzy and that can be set for 1-10cyl with a standard magnatic pickup.

but normally no you can swap between a rotor and v8,

with the new LT16 that is due in just over a months time i have heard that dealers can purchase the software to configure boxes.

Will the Lt-8 run the waste spark system on the RX7, cuz I need to keep it burning as clean as I can for the street.

Thats what the trailing coils are for, and the LT-8 can control em.

_____________________________________________

* Load
Sets the main fuel map for the engine via an inbuilt MAP sensor in the ECU. There 16 LOAD points ranging from 30"Hg to 20psi. (30psi optional)

* Idle
Sets the basic fuel map for the engine at idle. There are 8 LOAD points ranging from 30"Hg to 00"Hg.

* RPM Wide Open Throttle
Adds (or subtracts) a set amount of fuel when the throttle is wide open. The amount of variations depends on the engine speed with 16 setting points between 500 rpm and 8000 rpm at 500 rpm intervals.

* RPM Cruise
Adds (or subtracts) a set amount of fuel while constantly cruising. The amount of variations depends on the engine speed with 16 setting points between 500 rpm and 8000 rpm at 500 rpm intervals.

* Accelerator Pump
Supplies additional fuel and timing as the throttle is opened to allow crisp acceleration. This is a dual stage function, setup by adjusting the switch on and switch off points, as well as the amount of additional fuel required.

* Water Temp
Adds (or subtracts) fuel dependent upon the engine coolant temperature, to assist with engine warm-up. There are 16 adjustment points ranging from -25 deg to 124 deg.

* Air Temp
Adds (or subtracts) fuel dependent on the temperature of the induction air to maintain engine performance as ambient temperature changes. There are 16 adjustment points ranging from -25 deg to 124 deg.

* Cranking Enrichment
Supplies additional fuel while cranking the engine to assist with starting. Correction can be made at 16 temperature points ranging from -25 deg to 124 deg allowing for easy starting, hot or cold

* Timing RPM
Sets the main ignition curve for the engine. There are 16 setting points between 500 rpm to 8000 rpm at 500 rpm intervals. The ignition timing is adjustable over a 45 degree range.

* Timing Load
Adds (or subtracts) ignition timing while cruising, under load or boost. There are 16 setting points ranging from 30"Hg to 20 psi.

* Timing Water Temp
Adds (or subtracts) ignition timing dependent upon the engine coolant temperatures. There are 16 adjustment points ranging from -25 deg th 124 deg.

* Timing Air Temp
Adds (or subtracts) ignition timing dependent upon the temperature of the induction air.There are 16 adjustment points ranging from -25 deg th 124 deg.

thats the old specs, they now have the 16 load points every 500rpm
