Diahatsu HC-E 1300cc 16v ecu hunt

[sksobaid]

Assalam u Alaikum everyone. I’ve bought a charade which has Diahatsu 1300cc engine. Engine started doing missing whenever i press accelerator on high rpm. Electrician checked and told me it has toyota 4age ecu that’s why it isn’t working good with this engine and we need to change it. Changed the 4efe ecu and problem was still there. He is saying i’ll find a 1600cc engine’s ecu and we will try that on but I don’t think it’s gonna work.

Help needed

I need to find this engine original Ecu if anyone can help me? Refer me to someone who might have any idea about it. Sharing the required ecu pictures below

you may test an ecu from a 4A-FE engine

a Daihatsu 1300 cc ECU will be a tough call to source, as

I tried 4EFE ecu today. No luck with that. Is it possible that missing problem is not because of ecu? car’s spark plugs are all black too (probably means it’s using more fuel than it’s supposed to)

Here are engine pictures

If you can tell us what exact engine it is... We might be able to help... Keep in mind a Daihatsu 1.3 almost never came to Pakistan...

Contact the person you bought the car from check if he swapped the engine and from where he got it...

[sksobaid]

This is the engine’s clear picture. Engine Name is HC-E 1300cc 16valve. I know this engine never came to Pakistan. They said the previous owner changed it from Allah knows where

[omersiddiqui5482]

But the model you have came with these engines.. are you sure it has been swapped...

The ECU you are looking for is:

It will be very hard to find to be honest. It is available on ebay... Plz mention your city...

Also, some of the early Terious Kid Models came with the engine...

please check physical pin slots for a Toyota 2NZ FE engine from Manual trans vitz / yaris or a FAW v2 1SZ engine ECU

Thank you so much it was helpful.

Assalam u Alaikum. Thank you guys for your help. Uzeem bhai i’ll try this too. For the time being my missing problem is gone, apparently my electrician forgot (maybe not, who knows) to check fuel pump pressure. Fuel pump was chocked. My mechanic checked it and changed it with a new one and it’s working fine now. Actually i need a recommendation too. My car’s engine has only 3 mounts and it’s missing it’s fourth mount which is joint on the guadry on which the engine is placed. Any idea about the mechanic who can get this work done in LAhore?

Wailaikum Assalam
Any mechanic can get it done. You can take it to bilal gunj.

[sksobaid]

Thank you Hassan bhai. I’ll visit.

The hc e engine has a batch fire injection system, meaning all 4 injectors fire every cycle,

It uses similar crank trigger (crank sensor) as toyotas (2 wire vrs)
The ignition timing is fully controlled by the ecu via the large ignitor. The tps and map are all similar.

If you wish to fire the engine on a 4efe ecu, then you will need to make a custom/hand made wiring harness that supports group fire injector wiring and the distributor wiring compatible with toyota too.

Your current problem is most probably due to flaky crankshaft speed sensor signal (corrupted signal to ecu) or bad ignitor (corrupted igf also does it)

Also its wise to install separate relays for main ecu and fuel pump, even the g102 charade with this engine had a large fuse box in engine room and also hanging off the positive battery terminal. Because the factory ignition switch wiring was pretty bad on daihatsu charades.

[sksobaid]

Always a detailed answere. Thank you Xulfiqar bhai. I think i will just gonna make peace with current ecu. My G100 does not have a big fuse box m. I will share pictures insha Allah. What do you recommend i do to resolve the issues you mentioned. I am having hard time understanding most the terms. I don’t have much knowledge about wiring and all.

[omersiddiqui5482]

Check for the wiring diagram for the engine and the car itself... BTW where are you in Karachi..

[sksobaid]

I would have ti find it’s diagram for that. I am actually from Punjab not from Karachi

[Xulfiqar]

Sorry to sound harsh, but when you had no idea of wiring etc why did you take on such a swapped car task?

Btw

These oldschool toyota/daihatsu ecu have the pins marked on the circuit motherboard itself, if you know what they mean and understand how an efi car is wired you can make the wiring yourself.

You can make a cluster of relays and and hang a few fuses in place of the original fuse box of the g102 etc. The main battery positive fuse hanger is also cheap to source (lots of toyota and nissan used it)

@Xulfiqar on saturday i will be able to go through the manual and share the data with you.

[sksobaid]

Sorry to sound so naive. Actually I did not take on this swapped car as it was given to me. The missing issue is resolved now as it was just a faulty fuel pump. This is already running on 4age ecu, i am not going for 4efe ech now.

[Xulfiqar]

I would suggest to either rid of the car or completely and fully wire it up so you get maximum life and economy from it.

Its a pretty decent engine when working nicely.
