4AGE 20 Valve Blacktop Plug and Play Harness for Greddy E-Manage

A customer from Sarawak asked me to make him an E-manage plug and play harness for his 20v Blacktop 4ag,as he doesn't want to cut the original harness.

Used connector but almost as good as new connector

Here is the female connector being soldered to new wires.The wires i'm using is automotive quality AVSS 0.5mm wires.(Exclusive order, hardly can find this in any electrical shop)

Finished plug and play harness with wiring diagram for E-manage installation.Warranty provided for the harness is 3 month but it will last for years.

KE70 Restoration Part1

My KE70 restoration project finally started after 1 and a half month waiting for the workshop to clear.The car will be stripped and send to bodyshop for body repair.The body and chassis is in a very bad state as it is already 28 years old and have endured so much abuse.It has been driven to jungle,dragged and drifted.Rust is everywhere and the body have been repaired a few times.

Drift abuse and peeled off paint

The engine have been drag and drifted,driven like mad (8000rpm shifting most of the time), this Silvertop 20V (with Blacktop ECU) it is still going,allthough not as good as other 20V in term of performance..its been leaking here and there now and consume engine oil. It will be rebuild soon,still thinking what engine management i want to use.The engine bay will be painted too,and will be wire tucked.

Engine is out,wiring and all accesories next.

Finally after 7 years inside the engine bay and never been overhauled since..for the first time it is out of the car! Look at that gearbox covered with mud,a testament to drifting.

Hopefully this project will give new life to the KE70,stay tuned for updates!

Corolla SEG AE101 Blacktop 20V Auto + E-manage tuning

A friend introduced me to a toyota seg owner who wants to tune his e-manage.This is my first time dyno tune an auto 20v,it is quite difficult as it need delicate control of the throttle in order to maintain the car in particular gear,hence it is hard to get consistency on every runs.

None the less,the base run made is quite good and it is very hard for me to squeeze the every bit of extra power and torque.I got it after almost 30 runs,but there is a strange torque dip at 3500 up to 4500,i spend another 47 runs just to tuneout the dip but after using all tricks up my sleeve,still couldnt get it to better.I guessing this is something that can only be resolved on the street,as this car is auto transmission,and dyno loading can't simulate some of the load the gearbox experienced on the actual road driving conditions.

The AFR lean out just at that moment,i'm thinking it caused by vvt switching on.Something we couldnt see on dyno,a further street tuning should resolve the issue.However,there is an increase on torque right after 4500 up all the way to redline,is much flatter.Peak HP increase is quite minimal and happens a bit later than previous,but it still climbing up until 7600rpm,almost at the rev cut and shift point for the autobox.

I want to review this back and find ways to improve the torque curve and AFR lean out issue at low rpm,will be fine tuning on the road.But anyway,owner now happy with current performance.

Plug and Play harness for Microtech MT-8 Nissan RB20DET

My friend Zyfull is building a drift spec car and i was trusted to build up a plug and play harness for his monster.

All parts are supplied by Zyfull,now harness up and ready but i did'nt manage to get photo of the finished harness,maybe i'll upload it later.It is now already with Zyfull and ready to tune.
