only that it does not misfire anymore, all it cost me was a few hours of my time! im still amazed it actually worked

As the 1uzfe has two igniters I used them to trigger four coils each

The is200 coils are 4 pin

pin1. earth

pin2. igt

pin3. igf (not used)

pin4. switched 12v live

the earths from all 8 cop's were connected to a common ground on the chassis of the car, the switched live was fed to all 8 cop's, I connected the igt wires from cylinders 1 and 7 together with 4 and 6 to IGT1 on the 1uzfe igniter plug, I connected the igt wires from cylinders 2 and 8 together with 3 and 5 to IGT2 on the other 1uzfe igniter plug (i dont know if this is necessary, i just copied the way each distributer would have sent the spark to two cylinders on the left bank and two on the right bank) I still need to de-pin the igf wires from all the cop connectors as they are not used

Ive done approximately 20 miles as I drove it to work today, no problems to report so far!

Here are a some pictures of the is200 coil on plugs fitted, I cut off the mounts with a small angle grinder so they would fit in the valleys, I still need to make some brackets to hold them down and i need to tidy the wiring, all the connections are soldered and shrink wrapped.

It worked! Ive just been for a drive with the is200 coil on plug conversion working with the stock 95 lexus ls400 ecu, I had it on the limiter in a 3rd gear drift and it ran without fault, it revs clean throughout the rev range and idles fine, tacho is still working too!

pictures and maybe even a video coming a.s.a.p.

the first link i posted has gone dead, new one here http://forums.club4a....php?f=13&t=206

and another useful one http://s-86.com/s-coilpacks.html

the cam sensors were cleaned when i fitted the new rotors and caps, i got 8 free cop's today for the 6cyl beams engines in the lexus is200, ill report back during the week if it works or not.

I gave my local toyota dealer 90 euros for rotor arms and caps( and waited over a week for them) which have not fixed an intermittent misfire, next step is plug leads @ 300 euros

Im not looking for any extra power from the engine

On the 4age 20v engine I have seen people use coil on plugs with the stock ecu, I think it works because of the sequential injection.

Would this work on the 95 to 97 1uzfe with sequential injection

I signed up to say thanks for a great write up, I used this info to wire a 95 1UZFE with CE70 W56 box in my 1985 Daihatsu Charmant ( basically a ke70)

One thing id like to add was after wiring it I got fault codes for the o2 sensors and afm and it ran very badly using a lot of fuel, after a lot of head scratching I discovered it was not getting switched live at the airflow meter, I think when I chopped off the automatic transmission plug at the back of the left cyl head before installing the engine I might have cut the power feed to those sensors as it was the only mod i made to the engine harness. The sub o2 sensor trick works great too!

Thanks again and here are some pictures of the V8 Charmant from Ireland
