what will it be if i use a evo 8 ecu in my spyder, will it help with h/p???

 

I don't think it would work without a lot of work. Due to the newer sensors and wiring harness different. Now an Evo III ecu might work, but I'm not 100% sure.

 

for the amount of work/money involved, you're almost to AEM/stand alone territory. Doesn't seem worth it to me

 

it works..theres a thread on tuners somewhere. supposedly its an alternative for dsm link that works out cheaper. i think they had a couple of bugs but not sure if they worked it out.

 

The only reason you would want the evo ecu is for the ability to use ECUFlash to change fuel and timing maps..etc. It wont add power in itself. About the swap...

Its not plug and play. But its not hard either. Basically what you need is an evo 8 4 plug ecu. You swap some pins around in the plugs on the chassis side per the wiring diagrams on tuners. Its just a few, I think the fans and the fuel pump relay are the only ones that really matter..after that you reflash the ecu with a tactrix/evoscan cable to delete the imobilizer, change injector/maf scaling to fit the 2g...

As far as money...it costs ~$100 for the cable and $150 for the ECU. Thats more like SAFC2 territory John. Although hanging out for an hour in the passenger footwell isn't fun

Just go to dsmtuners.com and check out the engine management section. Theres a pretty good 10 page thread.
