I'm matching up a mitsi4g15 8 valve efi to an a15 and stuck with how to make the crank angle and tdc sensor work for the ecu??

The mitsi has these sensors run off the dizzy. Obviously the a15 has a point dizzy.

So can I use the mitsi internals in the a15 dizzy, or is there another way I can get the computer happy enough to run the injectors by aftermarket sensors.

All I need the ecu for are the injectors but I'm unsure how to get over this little hurdle

Take the points dizzy out
Throw a e15 electric dizzy in and run it as a batch fire

Or, leave the points dizzy in.
Run the aftermarket ECU in batch fire mode.

Here is a Nissan E15 dizzy with Mitsubishi CAS

Aftermarket ecu would be great but it of budget.
That e15 set up looks perfect. Do u have a thread of how you made it work?

Does the cas also read tdc?

Yes, the largest cut is for TDC detection. It is a factory distributor, see D4P.

Cause I'm about slow I've read that a few times.

So I get an e15 dizzy change the cog over from the a15 dizzy and get the mitsi tdc cas to fit in the housing.. Then the 4g15 ecu will recognise these sensors and work??

Just clarifying. Cheers

Yes, it tells you about the Nissan distributor with Mitsubishi CAS. It doesn't say anything about whether it works with a Mitsubishi ECU. Your guess is as good as mine. What does the 4G15 distributor matched to the ECU look like and what is the model number stamped on the distributor? Or what year/model of Mitsubishi is the ECU from?

The good news is it will fit into the A15. To fit any Nissan E-series distributor into an any late A-series engine, drill a hole in the shaft, slide an A-series dizzy gear on. Then fix up the hold-down bolt area. This is explained with photos at E15 Electronic Distributor Swap, section "Drill Method - Late Block" is how I would do it.

I have only found one engine at the wreckers which I got my parts off and it never had the dizzy
Will ring mitsubishi tomorrow for parts numbers as I'm struggling to find info online.

Is from a 89 mitsi lancer 1.5 sohc 8v efi. They had these engines from 88-94 in lancer, mirage, precis, and even hyundai. But hard to find correct engine as they had twin cam, 12v and carby within that era.

Well they sold an 8-valve here in 1989. They have a distributor and a separate CPS (CAS), but it is not a 360 degree type like the Nissan E15ET CAS.

You might want to post your question on DIYEFI or on lancerprojects (are there other CAS that work with the Mirage 8V ECU?)
