Since the old thread by the Jackal developer was deleted, I'll start a new one to allow people to continue to discuss the project, share experiences, and work out technical issues here in a new thread. If any critical information was lost in the deletion of the old thread, I do apologize.
"Jackal" is a software project developed by ds-map.net for tuning a 1G DSM using Speed Density - you will have to register an account at ds-map.net in order to download the actual software, as that's where the software is being managed and maintained, and probably where support could be found. As of the time of this posting the software download is free. But there are costs associated with going this route, as you'll see below.
Here is the content of the old thread, explaining what you need to do to use the software and how it works:
Speed Density: what is that? Basically Speed Density is a different way to calculate AIR FLOW without needing to MEASURE AIR FLOW. You calculate pressure from a map sensor, over rpm and volumetric efficiency against a table, instead of using a MAF sensor that restrict total air flow. So technically you can never max out speed density based on air flow.

Materials:
- GM-3BAR map sensor (MSD-2313) / Other sensors are supported (GM2Bar, AEM 3.5/5, etc)
- GM-AIT (MSD-2320)
- 3/8 NPT bung (38NPT-S), found at RRE's AEM page under Other Sensors
- A Moates Ostrich unit
Preparation:
- 1) You need to have your ECU socketed, a MAP chip (of course), a palm pilot, and the mmSD logger program.
2) Get the 3/8 NPT bung welded into your IC piping. Make sure to place it after the intercooler, and before any water injection. It can be on either side of the BOV.
3) Install an EGR block off plate. EGR will cause inconsistant MAP readings, because is is allowing exhaust into the intake. The ECU assumes everything in the intake is air.
4) Get a Ostrich which makes this project a real, realtime editing ecu...
like aem-ems.
Installation:
- 1) Disconnect the battery, so we don't bake anything.
2) Skip 3 to 4 if you just buy this wire harness, which is $39.99 from Fullthrottletech.comYou must be logged in to view this image or video.
3) The MAF wiring we are interested in is MAF sensor pins 4, 6, 7, and 8.You must be logged in to view this image or video.
4a) For Turbo MAF : Connect the MAP sensor A to pin 6, B to pin 7, and C to pin 4.
A goes to GB (green black)
B goes to GY (green yellow)
C goes to GR (green red)
For NA MAF : Connect the MAP sensor A to pin 4, B to pin 5, and C to pin 3.
not sure on colors for NAYou must be logged in to view this image or video.
4b) Connect the two wires from the GM-AIT to pin 8 and pin 6. It is a resistor, so polarity does not matter.You must be logged in to view this image or video.
5) You will probably want to put a molex connector from radio shack on rather than soldering everything directly to your wiring harness.
6) Put the Ostrich chip into your ECU, be sure that the half circle notch on the chip matches the half circle notch on the socket, and the one printed on the ecu. If it is in backwards your ECU will fry.
Testing:
- Starting it up: Make sure everything's back together, and reconnect the battery.
Turn on the car, but DON'T start it. The CEL should light up, the boost gauge will go halfway up. If the car makes a lot of clicking noises, or the CEL/Boost gauge do not read correctly, turn off the car and recheck your wiring.
Connect the logger, and set it to view MAP, IAT, and Coolant. MAP should be around 1.0 bar, and IAT should be equal to the outside air temp. If the car hasn't been run, coolant temp should also be about equal to this. If either of these are way off, recheck your wiring.
If everything looks good, fire it up, and drive off. The CEL and boost gauge will turn off.
