Volvo 360 ecu

Post by Bossie » 26 Oct 2011 11:19 pm

I´m looking for a Volvo 360 ecu. Need one so I can try to modify the fuel injection curve by changing some resistors.
If you´ve got a one and are willing tot let it got at a goof/fair price, please contact me!

Brave! Check the capacitors, electrolytics have a habit of failing after 20-25 years so will be worth checking before you put in huge effort. New RC constants will knackered caps will just have you chasing problems!

Presumably you want the Bosch LE Jetronics Injection controller, I do have a spare I'm not intending on using.

Just wondering why you want to change the fueling? If you are doing medium mods the current system should work fine, serious mods probably need a programmable modern system like magesquirt.

If you have one, please pm me!

Well I'm currently running a D cam, mvp big bore throttle body, T5 injectors, higher fuel pressure and E85 as fuel.
Every time I change somsething the engine starts to go lean. However my injectors even together with E85 should be big enough for 200hp. If the duty cycle from the ecu is right that is.Which it is not at the moment.
I have a flexitune piggyback which is an E85 converter I could use. But if I'm able to change just a few resistors I would be able to adjust the fuelling for only a few quid.
Next mods are an exhaust header, better intake manifold and maybe a B230. So I really need to mod the fuelling if I would like to stay Ljet. which I would like to, have swapped LH2.4 in a 360 before. This car should be a cheap beater. If I'd get rid of Ljet it would proabably be in favour of Carbs and a point distributor or maybe megajolt.

I'm hoping to LH2.4 my 360 :)

Are we talking about renix unit under the coil? if not wheres the ECU? :oops:

In front of the gearstick, side carpets come out of the footwell to get to it

not right, it just controls fueling?

Its not a digital computer, its an analogue one, so the relationship with the air flow can be changed by resistors.

Can you not just add resistance to the AMM to shift the curve up?

You've just described the infamous "power resistor of justice" ride on! No, its not a good plan, it'd run horribly
