ECU and wiring help TU5jp4s engine

[Happy Dane 1]

Hello fellows

I am living in Denmark, and the knowledge in the pugs are limited. I have decided to retire the old TU3 unit in my 205. I like grunt, but also a smooth running, and the choise was a TU5JP4s engine.

I have read some fantastic topics here, but are still missing some answers.

The engine is born with a locked ECU and a BSI unit. Beside this it have a throttle that is operated by wire, and not the old style with cable.

I am not happy with this solution and want to ditch these features.

What do you recommend of solution with the ECU and throttle ?

I can make the wiring, and could get the original Bosch ECU unlocked, but am unsure about it´s the shortest solution.

Beside that I am concerned about the tachometer. Can the tacho be connected directly to the ECU ?

Please help me with some advice

 

kind regards

Well

I did not receive any help/ respond to this topic.

The solution is a VTS ECU, that is unlocked by a specialist (UK) to work without the BSI and the anti-theft devise.

I will use the normal throttle from the engine (VTS), and change the car to the changes.

Engine will be fitted with a 4 -2-1 manifold, converted to fit the standard XS Exhaust, to meet the regulations in Denmark.

front subframe is 1,9 GTI and rear brakes 1,9 gti disc.

Dash is changed from XR to XS with rev counter.

The car will be a sleeper in summer, photo will follow.

Regards

Henrik

Thanks for updating your own topic.

 

This used to be a popular conversion so I'm surprised you didn't get any responses.

 

At least the answer is here now for anyone searching for the same thing.

he's using a multiplex system ecu, ive not come across anyone using those in the uk, everyone uses the jp4s engine with the older J4 ecu and inlet from the saxo/106.

Hi welshpug. Your knowledge would have helped, but in my country they are hard to find. I will break a 206 and use the loom. The ecu is from cartech electronics. The mot in Denmark is difficult to pass, but this solution should solve this. Is still inspecting and collecting parts.

Best regards

I did purchase this engine in UK. Took it apart and my suspicion of poor storage of the engine was right. This will take a few hours to solve.. the cylinderhead needs to get the valves lapped in too.

Get 3 angle valve seats cut while you are there

 

i don't personally like the electronic throttle, having owned a c2 code I found it to be a bit crap to drive spirited, the feel of a cable throttle is 10x better in my opinion.

With a cable the ecu can only follow what you do, you floor it? so be it.

With the electronic throttle you ask the ecu to floor it but it does it at its own pace for a smoother drive and less emissions.

[dcc 855]

Makes driving the car fairly boring in my opinion, if I say full juice, I want full juice!

 

That being said I also have an E46 M3 with the electronic throttle which seems quite more responsive to the throttle openings

[jackherer 543]

It depends on the throttle mapping, if you can crack the ECU you could make it do anything.

The Ecu is from a Vts and I have been told it needs the electronic throttle. I think it will be fun. I am used to flow heads and have the tool to cut seats. I will remove the burrs and casting errors, but dont have time for a full work. Pictures will follow...

Hello again. Is on the lookout for a VTS wiring diagram. Same as the tu5jp4s. Purchased the Haynes manual just for the same, but the diagram is not covering the engine.. ouch. Not easy to find on the web.. Thanks

[Happy Dane 1]

well its been a while. Engine is in the car, and the throttle is not the fly by wire, but a direct throttle. The ECU uses the same program as Megasquirt, and I am struckling with the setup. but will post pictures, as soon as its all put together.

Cheers

Still strukling with the setup. The ecu has byen a nightmare. Seller promised a lot, but the ecu can only run waisted spark. Engine runs, after changing the coils to NGK. Tickover is difficult with close loop, but is close. Car is completely changed to 1.9 gti spec. Engine bay is complete, but found this picture.

Hey Henrik, what ECU are you using?
