Which ECU for 390SE??

[hillclimbmanic]

I have a 4CU that came with the car...Is that for the 'Flapper' system, as I have a 'Hotwire' injection with my disco 3.9 engine..? (14CU corrected, so as not to incriminate myself as stupid!!)

Yeah im fairly sure you need a 14CUX for the hotwire.

[Wedg1e]

4CU is for the flapper, 14CU(X) is the hotwire version.

ETA: the 4CU is silver with the covers held by 6 screws; the 14 is black with only 4 screws.

I think i have a spare one if you need it, it was black if i remember so may be suitable for hotwire, i will dig it out and check.

I'll take the 4CU off you if the price is right...

[Alexdaredevilz]

Imo you would be foolish to spend money on any 14cu(x)

Just plug a aftermarket ecu in place, saves alot of stress in the long run and the improved fuel consumption would probably pay it self back in a year

But I need a 14CUX to give as part-exchange for a Megasquirt Unit...That's what I intend to do!!!

This one's got a Tornado/'Austec Racing' chip installed...

Just cut the old plug off and solder the new 6inch loom that comes with the mega squirt

Has it really. I'd like to see a pic of the inside of it then. It's impossible to 'chip' a 4CU. It conceivably might have a piggyback board added but in standard form it doesn't have a fuel map in the way that the 14CUX et al do it.
The 4CU is an analogue computer based on two Ferranti ICs that were designed for the job - so you can't plug anything else in in place of them.

[hillclimbmanic]

...or some K**b has stuck a Austec Racing label on this 4CU - What would I know???

[hillclimbmanic]

Photo is rubbish, and I can't post it...so

"Lucas Part No: 83986A Type 4CU Date: 16th Nov. '04
Lucas Serial No: 9478HPD MFG 4987 Serial: XED-89210-RVVT
3.9 Litre - Standard Injectors & AFM Calibration 0792/0920 E-DRIVE
TWO YEAR WARRANTY - INVALID IF SEALS BROKEN

Austec Racing Tel: [phone]

on the right side of the label is a cartoon Hedgehog with "Happy
Hedgehog"

On the top is an IBM Sticker with Dave Knight (AUSTEC)

Like I said, I don't know which way is up, yet...That's why I joined the forum

ONE MORE TIME...They will not sell me a Megasquirt, without me sending them a 14CUX first!!!!

Hi Jon...Sorry I haven't answered, I've been away...Yes, I received your email, thanks...It looks like I'm going to need some more information on ECU's, judging by wedg1e's answer!!!
