~Kinetic motorsports frontmount intercooler core is 24" long 12" tall and 3.5" thick

~ACT 2600

~ACT XACT flywheel

~FP 4" intake with cone filter

~Tial 38mm wastegate

~tubular exhaust manifold

~full 3" exhaust with Magnaflow muffler

~780cc injectors

~Walbro 255

~AFPR

~GM 3bar map sensor

~IAT sensor

~triple gauge pillar,
 
Someone finally picked up that car eh? One of the most knowledgeable AEM tuners in the country is in Portland, OR. John Reed. One of the best DSM shops in the country is in Camas, WA. Neither are close to you.

Is the tune off? You sure the wiring is complete and done right? The guy had the car partially taken apart and never had it tuned/set-up from what I inquired.

Ya picked it up for a better price than he was asking.

I put the valve cover back on, put the spark plug wires in, put the throttle cable back on, put a good battery on and changed all the fluids in it.

I attempted to fire it up an it cranked but no start.

I guess when I get home I will check to see if it was put in correctly.

The guy stated it was tuned by a buddy of his and ran decent.

Question I have is : With the car being down for so long does the AEM EMS computer retain the last tune? or do I need to retune the whole thing?

Just want to be able to get a decent tune and then take it to some one that can fine tune it.

Any more info you may have about this car?
 
Im not sure where granger is but you can try Forward Motion in Lakewood. He's a pretty knowledgable guy when it comes to Mitsu cars. He's located on Lakeview ave and 108th.

Ya after I get it running I will be taking it to English Racing for fine tuning. Thanks though.
 
Current tune should be on the car. It won't "lose" a tune unless it was erased. Do you have a spare stock ecu/setup to start it with just to rule out the AEM?

I don't have an extra ecu laying around.

If it doesn't lose the tune on it then I will go over everything on the car to ensure all is hooked up right and attempt to start it this weekend.
