    Also got my header ceramic coated and installed. A lot of piping work when replacing the former header to this one which involves a lot of modification of pipe and numerous trial & error of fitting problem when doing this on my own at home without any welding facilities. Have to do piece by piece and visit the welding shop numerous time as the car is stranded at home on stands. A lot time and effort put in. Car is in running condition now after been sleeping for a long time.

    Not bad of a job however could be more professional if they were to work the details such as remove the machining burrs and wash the parts after completion. Otherwise would be great piece of work when someone would take all the trouble to make such a cheap alternative than buying the OEM imports.
    Here are the photos...........yet to get it installed and test out. Will need some run in to perform well.

    I.. yah......this is the 3rd. time I am trying to post some work done on my project and always could not get it done correctly, this showed that I am away for too long .............hope this time will work.
    All this while I was having problem as my Mac Air book was acting funny and have to reformat. Lost my USB to Serial RDS232 comm link. Tried numerous time to finally downloaded the correct software that works with my Mac.
    Upgraded to MS2 with daughter board and loaded with ver.3.3.2 firmware. See attached photos.
    Added an external heatsink ( overkill ) which will help to keep my injector driver cool. See photos.
    Replaced the serial connector to higher amperage connector. See photo.
    Was having issue with RPM synch with my crank sensor and finally bought and paid the paid version Tuner Studio and problem gone, I got RPM synch with my crank sensor ( actual live tested ).See photo.
    This show "no free lunch" is better. Anyway those dudes spend their sweat & time needs to get their lunch paid which is fair !!
    Tested RPM cut at 7700 rpm, spark cut works perfectly. Its good to test with the stimulator and ensure all function works before installing than to ruin the engine. See photo.
    Tried to attach photos...........hope it works............:driver:

    Next will have to figure out how to run the wire loom, relays, fuses etc. Coil pack installation is another headache, where to put it? Any suggestion? Will be using back the spark plug cable ( TRD ).
    Planning to modify the intake manifold to side feed as the mid feed is having uneven distribution of air since #2&3 cylinder will always run leaner. Hope with a side feed will solve this issue. Also to modify an intercooler to top mount for the shortest pipe run. Wow........looks like tons of work........for DIYer.

    ya lah......project took so long.................air water intercooler good initially but once heated up also takes time to cool down. Thanks for the suggestion.
