Where does the rpm (rev counter) get its feed from
I am installing an lpg kit to my jaguar, and one of the requirements is to take a signal for the rpm.
On that basis, the car has individual coils so taking a signal from one of these only gives you half the true rpm speed, ie dash shows 700, the individual coil shows 350. as the coils are constant +ve feed and switching -ve earth (as far as I can tell).. On that basis, if I 'piggyback' the -ve for 2 coils,(which may give me the full rpm signal) I suspect this will not work as the signal from one coil pack will travel down the wire to the other coil pack and cause an issue with the car's ecu.
I would greatly appreciate any opinion on this issue.
great car though.

It is normal. All LPG converted engines start with gasoline. Then when they reach 2000 rpm move on LPG system.
If you want to start directly with LPG must call a professional to modify your installation.
hi your issue is that your car which starts with petrol then switchies over to lpg for which youll already know ,but the problem lies within the cylindar heads as it can only be 1 of 3 things =1, your valve seals are worn excessively due to the lpg as that runs at a higher heat density which stretches the valves which in turn causes then to wear and that reduces the power ie lack off,as it puts the ecu into limp mode (safe to protect your engine) as its a common fault on ALL lpg conversions.as that is also the knock on effect with your master servo (brakes).as i fix approx 3/4 a month. hope this help's to clarify what is wrong ok
I doubt if there are LPG kits available for Diesel engine? LPG is for petrol engines only. However there are other kits available which will partially use LPG and diesel to run engine, these are not popular.
All LPG kits are custom to vehicles they are being installed on. The possible problems are the same with all models. They include Leaks, lose of Mileage and the obvious dangers of filling the tanks when needed. I will tell you this much, it is unlikely you will save any money converting to LPG as most conversions get far less mileage than they do on regular fuel. Also, a Conversion kit is a full conversion. Once installed you are not going to have the option of switching between the two when the LPG system fails. You would think with the faster burn rate you would have better acceleration in LPG vehicle and better Mileage since the Typical LPG fuel is a higher burning and cleaner burning fuel but in reality it it usually just the opposite in conversions and they have a tendency to vapor lock more often.
lots of old cars were + earth but not all .dont think this will make any difference ,is this rev counter for a 6 pot or four?? check terminals on back of unit??does one look as though it the earth ?? if not then one goes to earth and the other goes to the points side of the coil.easy
