Good luck!

keep us posted!

hi again, as you're in Holland dya have any info on the factory fitted 340s that ran on LPG? If they were B14 3Es and onwards I'm thinking the Renix has "built in" LPG map. LPG needs ignition retardation and I'm wondering if the 6 degree map was what volvo used for the LPG cars.....it just so happen...

hi there Here's a link to Mac's article http://volvoforumsrepairs.org.uk/300Repairs/300renix.htm Indeed as you say terminal C is the one with pins 6,7 and 8. Given that the 402 was fitted to the B14 3E and the 4E, one can run 3E's on 95 octane by earthing pin 7 and retarding the map by 4 degrees. Fr...

hi there

speak to the Daf Owners Club in Holland as I expect they still supply these.

From Mac's article on the Renix "However - one tip - If you run an 84,85,or 86 year car with a Type 402 Renix and suffer pinking on unleaded fuel you can retard the ignition timing by 4 degrees by earthing terminal 7." See http://volvoforumsrepairs.org.uk/300Repairs/300renix.htm Looks like the catal...

ok...bit of digging via SAE and various other university papers and research publications.....retarded spark reduces NOx and HC and has little effect on CO except when very retarded the CO will increase. These are rules of thumb though of course. This extra retarded map for the catalyser cars makes ...

ta da! It here in the tech section...wierd the search didnt find it though

PS where did you get the info on the catalyser models have a further 3 degree retarding ignition map from??

Hi there Seems then the Renix has even more capability than the two maps above. Initial info shows that the extra retarded ignition in the catalyser models is probably due to the fact a more retarded ignition decreases NOx and HC. Need to check affect on CO as well. As far as I'm aware the catalyser...

but earthing the middle pin gives a different control map for 95 octane. No earthing means you have a more advanced timing map which is suitable for 98. Earthing the pin on the B plug (only for later Renix units) is volvo's conversion for unleaded. It may not be the case for all Renix units though.....

from the Renix table this looks like the dual map Renix. Earth one of the pins (I think middle one) to make it run on the 95 octane map.

B14.4E = 412

anyone?

hello I dont know off hand the octane rating required by the PV651 but I generally recall the PV444 was designed to use something like down to 85 octane. Indeed, pre-tetra ethyl lead (American company supported by General Motors and the American government at the beginning) cars are fine on unleaded...

hi there Coming into this discussion a bit late but I asked a question about valve seats to a chap who used to work for Volvo BV (last project was designing the layout of the 480 engine bay) He said (as other have said too) the B14 1E and 2E have soft valve seats and therefore need lead or a suitabl...
