I thought I'd post some of the most relevant info from those threads just to make this thread a bit more complete. The dsmtalk thread has a huge list of all of the cars which you can get the GM MAF from that you will need. Anyway, here are the comments that the ramchargers guys made about their product:From mike at ramchargers:
"Here is the skinny on MAF's, we recommend and support 2 different units:
"The unit can calculate fuel delivery based on airflow and rpm this gives quite a bit of flexability in fuel delivery it is very easy to tune and eliminates the need for an AFC to compensate for mods or different size injectors."From Bob at ramchargers:
"The unit has 5 adjustments:
BASE 10% rich to 65% lean in 5% steps. use this adjustment to correct the entire range. This is the adjustment for injector size / fuel pressure/etc.
IDLE 35% rich to 35% lean in 5% steps. This adjustment is for compensating for open PCV, vaccuum leaks, fuel pressure problems, etc.
MID 35% rich to 35% lean, this adjusts the fuel delivery between 1 psi boost and 8 psi boost. Adjust for best response and spoolup.
WOT 35% rich to 35% lean, adjusts fuel delivery over 8 psi.
AUX 35% lean to 35% rich. this setting is factored in when trigger wire is energized. It can be used to add fuel for dry N2O applications or remove fuel for Alky or propane injection setups. "
"Injector size, adjustable from 10% smaller that stock to 65% larger in 5% steps. This will allow for fuel pressure variances and other factors. Install the injectors, set the base correction and go"
idle = Airflow below 10 grams/sec and rpm below 1500
cruise = base setting
mid = boost > 2 psi, all RPMs
WOT = boost > 8 psi, all RPMs
for default mode (rpm signal not connected) then idle is MAF under 10 grams/sec, mid is airflow > 65 grams , WOT is airflow > 120 grams "
"Ok, the thresholds determine which adjustment dials are being used for airflow correction. The dial selection thresholds are dependent on the RPM signal, the correction factors are not.
Base is always used since it sets the basic injector correction.
at idle you get base + idle correction
at cruise you get just base
at 'mid' you get base + mid
at WOT you get base + wot
if the trigger wire is activated, wot = base + wot + AUX.
We estimate boost using a fancy calculation that takes into account the engine operating conditions (one of which is RPM).
(like the stock ECU does to determine what to do with the boost gauge)
Without the RPM signal connected, we can only select the proper adjustment dial using airflow."This is what their website says about it:
"The MAF Translator will allow the use of a GM MAF sensor on the 1G Talon and Eclipse turbo cars. This low restriction unit will drasticly improve spool up time and air flow. The Translator will also allow for full fuel control so that you may tune your car for changing conditions or modifications. You may also compensate for different injector sizes when you reach the time for an upgrade. Simple plug in installation plus 1 wire tap is all you will have to do. A 3 sensor, cone filter and the Translator can be installed in about 20 minutes on the stock flex hose in the stock location. Fuel tuning has never been easier and with this installed you should see a significant performance improvment. We have the sensors, filters, silcone transition hoses and whatever you may need to complete the installation. If you have questions you may call us toll free at 888 293 7267 or send an email question to us at DSM HELP The translator comes with complete instructions on how to get started using it. When installed on a 1G car the Translator allows you to chose from a 3 sensor from the Impalla SS or the 3.5 sensor from the LS1 F-Body. "

Hope having all this in one place helps.
