I would say try scaling the 2G one first. It should work fine, but if it doesn't, then you could go with an EVO MAF.

Lots of questions
Are you running the evo8 maf with this?
Have you noticed any difference in drivability or other weird stuff?
Does the electronic boost control work, i saw some tables when i was going through a tuning tutorial for ecuflash and apperently you can change wgds and other bcs values...wonder if the 2g bcs is compatible to do this.
Wonder if its possible to run a GM maf by changing the values in the evo8 maf table...
I searched the thread and couldn't find anything about injector sizing.
your using 450cc injectors and the evo ecu is expecting 560cc injectors so without changing the fuel maps you's probably be logging lean, the deadtime is the same though. How did you deal with the difference in size of the injectors?
Also phantom knock, i saw some PK counts in the logs you posted...has it gotten better or worse since you did the swap? On this note, i never hear about the evos having partial throttle knock...wonder if the knock sensor from an evo would be an upgrade for us 2g guys...
i am looking at picking up an EVO ecu here pretty soon so i will have some questions i might need answered. my setup will be a little different, i have a MAFT Gen2. but for now i was just curious if you had seen this yet?
It's alive! (Speed density, stock ECU) - evolutionm.net
I'm fairly certain (though not completely) that 95-97 turbo cars did not come with the diagnostic port. I believe all 2g n/t cars have them and any turbo car with a plastic case ecu (98/99) will have one. I have no idea if 1g cars have anything like this. I also have no idea about the n/t spyders but in at least one case in the thread I linked there wasn't one.
I have a 95 Talon AWD and it dose not have the re-flash port so when I re-pined my patch harness to do this swap I just cut wire 79 out of the harness and used the half of the wire thats on the evo8 ecu side of the harness and connected it to the tantrix cable I was able to link up with the evo8 ecu with no problem well I did have one problem the evo8 ecu I got from a freind was bad and would not start the car so now Im looking for a good one (he had swaped out his ecu because his evo would not start when he installed the new ecu he found some wiring problems so he was not sure if the ecu was bad or not )I'm fairly certain (though not completely) that 95-97 turbo cars did not come with the re-flash port.

So I finally made it out to my car today and verified that I do not have the secondary diagnostic port, I believe I have all of the information that I need to install one when the time comes and we get out of sub zero weather but I just wanted to clarify that I'm looking for the right part since I have never actually seen one. If I am correct I am looking specifically for a white 12 pin connector out of a 98/99 turbo car? It seems like the n/t cars have these and they look the same but I'm not sure if the wiring is the same for them.
What I'm looking for is labeled "b" here correct?
I found some information about it in this thread.

If someone happened to have a picture of the accompanying wiring coming off of it or if it is just a single wire which pin it is attached to that might be helpful also though maybe it isn't necessary.
I followed the pin on an EVO wiring diagram and found that the corner wire that hooks up to the tactrix cable is a Ecu chasis ground. I believe if you can go find a connector at a junkyard cut it off and chasis ground it you will have your second port. Since the tactrix only uses this to ground itself for flashing/logging. My N/T spyder did NOT have this port I took it off a 2gb 420a car in the junkard.
I understand that it is simply a matter of providing +12v to that pin at startup and that there is an easy solution. If I have to I will just do that but I would like to have the actual connector. I think I've found one from a local so hopefully I'll have one soon.
Activate the CPU with a reset. (Activation from user program mode is possible by applying 12 V to the Vpp pin during the reset, i.e. while the RES pin is low*2.))
My tactrix only has 1 wire in the connector not 3, but it is the one that requires the ground (pin 79). Thats all that connector really does, which is why you can just pick up a connector and ground it out and it should work correct?
Alright, I assumed that it was a matter of applying +12v because of Madman's post in the ecuflash tuning thread for the 98/99 ecus. I guess that this is a bit different.
Well, I finally got the time to put an EVO ECU into my car. It works great! There are a couple of things, like the RPM gauge dropping when pushing on the gas pedal, and the factory boost gauge not working, but those are minor. Overall I am very happy with the way the car runs. Now I need to do a little tuning to smooth it out.
