Hello all, I'm a newbie to this forum but a longterm lpg 'convert'....

I urgently need a replacement BIGAS ECU, which is of the following type:-

COD.AEB2001 BIG
B0100287 39/1/1
06-11-01
MADE IN ITALY
A.E.B.srl
Tipo A.E.B.2001
BIGAS
Sequential Gas Injection System
E13 10R-020775
E13 67R-010157


The reason is because oil from the Inlet Manifold has become ingressed in the ECU vacuum chamber, and now I'm getting wildly fluctuating fuel mixtures which cannot be corrected by the Software Map.

So if anyone knows where I can obtain one of these units, I'd be most grateful.

Thanks,

Steve

Can't you clean it out? Squirt carb cleaner using the thin nozzle inside the chamber, give a shake to move it around and then pour the gloop out. Try that 2 or 3 times until what comes out is clean and see if that has cured the problem.

Otherwise, Tinley Tech specialise in Bigas.

Hi Gilbert,

Many thanks for your reply.

Yes, I did think about a clean-out option; I had in mind to gently squirt in some isopropyl alcohol using a syringe and needle, but was a little concerned about whether this would damage the vacuum chamber in some way. I think perhaps I should take the plunge and open the ECU to see exactly what this chamber looks like and what it is made of before going any further (I assume it must be a rubber bellows or similar inside); I think is is essential so that I don't puncture the vacuum chamber with the needle...
Anyway, I've got nothing to lose by trying the above as the ECU is not working properly right now!

I have already contacted TinleyTech, but they say this unit is no longer manufactured and supplied.

I'll let you know how I get on with a further update.

Cheers,

Steve

BTW - Gilbert....

I finally managed to get hold of a syringe and needle (don't ask how - have you any idea how difficult to ligitimately get something like that these days?....).
Anyway, I opened up the ECU and saw that there is a tube that goes to a vacuum sensor mounted on the PCB. I replaced the tube because that was full of oil, then squirted inside the sensor with isopropyl alcohol. Initially, some oily black sludgy drops came out before the alcohol continued to come out clean. Put it all back together with a new piece of tube; mounted the ECU in the car, but still no joy - car still runs rough on gas.

So a new ECU is still required, I think.... Thanks for the suggestion anyway!

Cheers,

Steve

I have a friend who is a midwife who usually has a load of them rolling around in the boot of her car...... Alternatively, I understand that they will give them to you if you go into your local health centre and ask. I suspect they'll take you more seriously if you don't shave or have a bath for a week before going in and wear the scruffiest clothes you can find.
