A friend of mine just installed a Vortech supercharger on one. Goes real well, but the spark timing curve is incorrect, of course. This is a MAF setup, of course. Can timing still be mapped according to MAP? Can he substitute a 2 bar MAP for the factory unit, and re-set spark tables accordingly? There is a product out that allows easy re-programming of the factory unit. I need to find specific info on the tables in the beast, and if it is possible to make it understand boost via a a positive pressure MAP sensor, or if timing is mapped via MAF alone. - - Clay - ---------------------------------------------------------------------------- To unsubscribe from diy_efi, send "unsubscribe diy_efi" (without the quotes) in the body of a message (not the subject) to majordomo@xxx.org ------------------------------ Date: Mon, 3 Apr 2000 11:11:04 -0700 (PDT) From: Clay B Subject: Static electricity and Teflon fuel lines I've heard this is something to be concerned with?

Haines" Subject: Chrysler Prowler gauges (in an LS1 equipped Prowler) Does anyone have any experience working with the electronics system architecture used by Chrysler on the newer vehicles? We have installed an LS1 engine and Corvette rear suspension and AT transmission in a Prowler and we are having a problem getting the engine coolant temperature gauge to work (it only updates on key on). We have left the Prowler body computer in the vehicle to control the dash, rear view mirror, windows etc. but the engine and transmission are controlled by a GM PCM. We installed Chrysler sensors for oil pressure and engine coolant temperature (in addition to the GM sensors) and feed this data into the Chrysler computer (like it normally would be). The oil pressure seems to work (although it seems to update very slowly). The ECT gauge seems to show the correct coolant temperature at key up but then does not update as the engine warms up (if you key off and then on, the new temperature is then displayed). We would like to either find out what is keeping the system from updating the dash or just change the Chrysler gauge electronics to read directly from a standard GM sensor (not having to go through the Chrysler computer at all). Anyone know of a company or individual that might be able to help us out with any of this?

I don't know if it's appropriate to ask the following from this list. If not, I apologize. Use is strictly for at the track. My truck has a MAP speed density setup. I bought, over the winter, a custom programmed computer (programmed for a blown/juiced Ram 360 but computer is for a Dakota ... excellent price to take the gamble). My truck is mildly cammed with beefed valve train components, headers, ported tb, K&N open air cleaner and free-flow cat-back exhaust. Testing on the street with a scanner, dynoed last week and at the track last Sat. At the track, the scanner shows that from the line, spark advance drops drastically from 32 degrees advance to 16-19 degrees at WOT all the way down the track (to be expected since computer is calibrated to run 10 lb boost and 150 hp juice shot without detonation). Street testing with scanner shows that timing is not retarded when not under WOT conditions. In general (not vehicle specific), can I send a MAP and/or TPS signal to the computer so that it does not know that I doing a WOT? or is it a lot more complicated than this? Again, I emphasize that this would be for track use only. Thanks for any insights. Bob.

Again, > I emphasize that this would be for track use only. > No. The computer is using both of those signals to calculate fuel, so you will lean out things and maybe damage something. To know what may or may not help you probalby need to know which map (in the computer) was modified to get less advance at WOT, and exactly what kicks in the less advance, but probably what kicks in the less advance is also used in the fuel calculation.

I don't know how unusual the pcm system is on the Prowler. When D-C redesigned the Dodge Dakota truck in '97, they completely revamped how the dash gauges received signals from the sensors. Prior to '97, wiring went directly from sensor to dash pod. In '97, sensors sent signals to the pcm, then the pcm sent signals to another 'computer' (the Central Timer Module), then the CTM sent signals to the gauges. The CTM on the Dakota is located at the end of the passenger-side dash beside the glovebox. Maybe this will help. The Prowler is a mish-mash of off-the-shelf parts from D-C. Maybe there's a FSM available for it. Bob.

A gentleman had asked about gauge problems after installing an older computer in a newer Dodge pickup, and a fairly good reply was given. It should be in the downloadable archives. Shannen Jason R.

Can't help with the electronic stuff, but do y'all have any pics of the beastie yet? I gotta see this!
