volvo penta renix control unit

Post by orrido » 20 Sep 2013 07:46 pm

Hello to all,
I'm Stefano and I write from Italy.
I have a big problem with a volvo penta engine and I think only you can help me.
the engine is a aq 171 2500 16-valve carburated and I burned the Renix .
the ignition module is the code 430 and can not find it.
I solved temporarily with an ignition module renault code RE292 but I think the ignition timing is not correct.
I found a map of the ignition module volvo penta I write below:

850 rpm 10 ° + - 2 °
1500 rpm 14 ° + 2 °
3500 rpm 23 ° + - 2 °
4500 rpm 24 ° + - 2 °
5500 rpm 31 ° + - 2 °

Can anyone help me find a Renix ignition module that has approximately the same ignition map?

Thanks in advance
Stefano

Hello Sir,

Volvo Penta is for a boat (we do cars on here) so I think one of the marine forums would be the best bet. Talking of Volvo Penta's, every 7 years I have to change someone's S-drive seal which always brings a sense of dread.... its just like Halley's comet.

Best wishes, bogbasic.

There could well be a 300 series renix unit that is close to your AQ171 one.

Mac did post up details for some of the 300 renix units that you could compare to.

I would not mind your engine btw.

I know that this is a forum for cars, but I can not find information to solve this problem.
I think this forum is the right place to find the correct information.
classicswede ...
can you put the link to the post of Mac please?

thanks
Stefano

the problem with the AQ171 marine engines is that they don't use vacuum advance for the ignition, the unit itself doesn't have the vacuum port.
all car mappings are based around the vacuum port so finding one that matches without it would be a case of trial and error, then you'll be better off if you convert it to 123ignition or similar

are you sure it is the renix unit that is broken? if the coil is dead you can simply replace that for a new one

I'm sure, I also tried to remove the resin under the Renix and you can clearly see a burnt part.
I'm currently using a Renix renault clio 1.2 type 292 with vacuum advance disconnected and it works, but does not have optimal performance.
I should find a Renix that, with vacuum advance disconnected, has a map similar to the penta ...
you think it's possible?

The problem I see is that non of the 300's had a 16V engine.

That engines nearest car equivalent was in the 700 series, though I'm not sure what ignition it used. Different markets got different engine specs based on local taxes, I seem to remember Italy got a lot of 16V redblocks? Might be worth a look at least.

is true, in Italy there are many 16-valve engines but have not Renix ignition ...
I think that 16 valves or not, the important thing is to find a Renix with ignition advance similar to volvo penta.
Do you think that there be one?

also a small number of late 240's with carb engine were equipped with renix ignition

wow ... thank you very much.
I think that the type 401 or 402 can work properly ...
What do you think?

yeah it looks like it's quite similar

the 401 unit is used on 340's with B14.3E engine, the Solex carburator type
the 402 unit is used on 340's with B14.4E from modelyears 1984 and 1985

Different approach is to use pragrammable ignition used for converting to CNG adn LPG.
I have experience with TAP 01, AC STag, from Poland and it works as designed.

You connect it between orginal crank sensor and Renix box and through windows software change ignition curve as you like, advace or retard so make your own curve best suited for engine.
It should cost around 50 euros.

As you are from Italy ask for similar device made by AEB.

Tap works either with MAP sensor or without it.

I use TAP 01 for Volvo B230FT converted to LPG. (Bosch system).

AC gaz poland is manufacturer.

and still rolling

thanks to everyone for help, yesterday I tried to remove the resin under the unit and found a burnt part. I brought it from a friend who works in electronics and he replaced a resistor and ... it works :D :D :D
now I have to fill the unit with something that looks like the resin that was there.
any suggestions?

Before you do, can you grab a couple of pictures of the circuit board? What did you use to remove the resin?
