I am having problems passing 120Mph, I want to go faster, my 03 civic Si was faster, anyway I bought HKS SLD type I because my car is a manual 1992 SC300 with a 1jz, but for my surprise when I was going to do the wiring on the ECU and is auto, and the pin out was different from manual ECU. So I am stuck now, but some how probably I can make it work just need some input or help finding the correct wiring if is possible or someone did it before, for what i research probably ECU is from a chaser, check pics below please I want to connect it the right way so don't fry my ECU.

ECU pics.









ECU plugs.





On this plug I think this the speed wire can some one confirm this?



HKS SLD according to the manual for 1jz all the set up buttons should be up, the manual is on Japanese so is hard to understand it. Any one know how the set up should be?



I found this auto ECU pin auto is this correct one for my ECU or they vary by the year of car or motor?

pretty similar for all years in terms of ECU pins. Look for pin SP1 or SP2 and check to see if it's the speed sensor from the sensor side.

 

Well according to your info, other like 25 web pages I came to a conclusion and start the experiment, I cut the pink wire the SPD, still got signal to the speedometer, later on saturday decided to cut other wire the SP1, is like pink or peach cable and is down a purple cable, weirdest think is I still have my speedometer working, no check engine car runs good, so I decided lets go for some pulls and yes I make 150Mph but I think i need a tune or something I have to gradually let go of the gas when I am 140 motor acts weird or cut off probably not enough fuel or is not properly tune to go at that speeds, car feel nice very stable, I have a video I will see how I can post it so you guys can watch it is night so don't expect a high quality in the other hand I have a MapEcu2 I don't now if it will work on cars with only ECU with no piggyback but you can try at your own risk.
