You are wrong, the propane conversion is still a huge issue. In order to do that conversion a lot of things get changed. The big one is that they can reflash your computer back to OBDI instead of OBDII (at least in Canada). That is about the biggest issue you can have. There will be other things done too. Propane burns cleaner than gas and the by products are different (read what comes out the pipes).

If you want the right answer you have to give all the info, not little bits and pieces. Your problem will be the changed info in the ECM. If you don't tell people the car had propane then they would not even think about that possibility.

Your limp problem is more than likely as result of pulling the propane computer. The second computer would have tables for looking up values. So now when ECM 1 looks for a value the table it is looking for is not there, because the 2nd ECM is not.

yes, as i said he needs to get the dme reflashed back to stock.

Did not see yours till after I posted. Good call

Ok checked my system - its only two years old and checked with the fitter its ecu is NOT reflashed - the system simply switchs the petrol injectors to gas injectors and thatgs pretty much it lets the stock ecu do the hard work... if you dont believe me google Romano RISN and you will see they have come on a hell of a long way...

The limp mode also happened as a result of trying to repair some broken lambda wirining, i pulled the propan system long after to check that it wasnt anything to do with... Whenever you mention propane people assume its that....

anyway slight progress......

Todays i have spent the day wiring the sensors as per the wiring diagram from WDS... The heating elements are still coming up as faults however i know these arent necessary to work , the signal is coming backi believe as the voltages are now fluctuating, but its still going into limp mode any ideas? below is the error history and some inpa screen grabs....:

Thanks

Idling screen shot after a few mins they all settle down around the same area...

at 1500rpm...

Any ideas why id still be limping?

vantaam5 · 2nd May 2011, 21:19

Looking at the coolant temps,they suddenly go negative....

Is your ECU flashed back to stock yet?

pyro225 · 2nd May 2011, 21:57

No and TBH i only posted that as an update really to see if anything stood out.. its booked in for this week for latest firmware to be flashed on and set back to stock ... that right yea?

Thanks

Any chance the fuse for the O2 sensor pre-heat has been blown? Fuse should be under the ebox as I recall.

pyro225 · 2nd May 2011, 23:47

Cheers ARD.. it was blown before i rewired it all in today...i switched it for a new one and its still reading like that and the fuse hasnt reblown...

Sailor24 · 3rd May 2011, 00:54

Have you checked to see if you have volts for the heaters at the plugs? Have you checked for a ground?

Temps look strange even the hottest mentioned at 78 may not close the fuel loop status?

pyro225 · 3rd May 2011, 21:52

hmm... didnt realize they were minus figures on that obscure error... might disconnect the water temp sensor to test it when tht not in unless that sounds dumb?
