Lancer RA reflash ... in a different way
Since here in PR we are far away of getting the reflash for the 04-06 Lancer RA ECU
I tried something different on a customers car
First we got a Mirage LS engine harness, Eclipse 98-99 ECU, some 4G63 sensors, EVO VIII throttle body
Second the engine harness was stripped out leaving just necessary stuff for running the engine
Third installed everything with all relays and stuff. Also a RPM switch was installed for MIVEC.
Fourth started the engine managed the idle and some stuff then went to the dyno
Idle
Dyno Run
Dyno graph
At first it was kind of hard to get it running but at the end it was easy
The ECU is flashed with a speed density ROM so there is no need of a MAF
Throttle response has greatly improved
Stock ECU and harness is in place
Gauge cluster has RPMs and Speed like stock
MIVEC starts @ 4000rpm
Dyno runs where in 4th gear
Everything works perfectly
Wanted to share this with you guys. Enjoy

It has:
-Intake
-Light Weight pulley
-EVO throttle body ported to 65mm
-Shaved head .060"(not a good choice)
-Adjustable Cam Gear(10 degrees retarded due to shaved head, made more power this way)
-2.5" Downpipe, stock exhaust piping with Magnaflow 2.25 oval muffler
-Speed Density reflash

Nice numbers! I have a few questions though: how much did it cost to make this project (engine harness, Eclipse ECU, sensors and EVO throttle body)? Is the EVO throttle body absolutely necessary or can you get the same result with the stock one? And, are you willing to perform this in another car? Greetings from Toa Alta

I'm trying to find a cheaper way to do it using stock engine harness
Using stock engine harness the cost would be like $300 including my work
The EVO throttle is not obligatory but you will need a drive by cable throttle body
