LPG Question.

[richrolls]

Okay. A simple one I hope. STAG Q-BOX Plus or KING A.E.B MP48 OBD lpg ecu? Anyone had experience of either please?
Thanks in advance.

A.E.B is a type or generic programming for many ECUs, alot of LPG systems are based on this (including Landi, Romano & Zavoli to name a for.

KING I have not come across but STAG I have. I would probably go for Stag myself.

Alot of people will say to go for Prins, BRC or LandiRenzo systems and to avoid 'budget' or middle of the road systems like Zavoli. IMHO (and with 400ks worth of driving experience behind LPG cars) IMHO the installation is paramount. I proved (or at least to myself) that a correctly installed mediocre system (like Zavoli) will give a BRC system a run for its money if shortcuts are taken with the latter system, which will in time (and on a regularly used vehicle) cause all sorts of hideous faults).

As an example, take my old Mondeo V6. In the engine list in the ad almost all of the parts were changed due to poor installation. I could go into the reasons why but I shall leave it there. The next V6 I had with a lowly Zavoli system went on to do 260k until some twit wrote it off with half of the faults (and the original engine):

Getting the correctly sized vapouriser and injectors will be important, injection systems are a bit out of my comfort zone where installation is concerned though. Stag has been around quite a while so there should be good info on the net. Have a look on the LPG discussion forum for loads of opinions.

Thanks.
I run an LPG car already which is getting replaced. The new'un is going go LPG as well. Unbeatable miles per pound I have found!
I am just trying to settle on which ecu. OMVL are the chosen injectors/solenoids. I'll be fitting it myself and then getting it certified (although not a legal requirement..) to keep the insurance options fully open. Some will not insure without a certificate. Oh, And the Stag stuff has a 5 year warranty which shows a good confidence in the product.
I have to save as much money as possible to spend on big old knackered British tin..

I am not sure it is as simple as mixing and matching injectors with other brands. Have you seen whether any of your kit works or are you going on a seller's word?

[richrolls]

Chas you are right. You have to make sure every component is compatible with each other. Some injectors/solenoid have temperature sensors for example. It doesn't all have to be the same brand. I'm buying new to be able to get it ticketed re insurance. Again, not a legal requirement (the ticket)but through experience I have found a few insurance companies want the car to be on the LPG register. To get it tested, the tank needs to be age plated. The advance in lpg ecu's is coming on leaps and bounds to keep up with modern electronics and efficiencies on cars. There is no real saving to be had now buying second hand LPG systems for modern cars.

Just out of interest which insurers have asked you for an install cert? Allianz did this year for the OH's car but they are the only ones who have so far in the last 20 years of LPG motoring.

[richrolls]

Orginally Directline. I have since been asked by Kwikfit and RAC was it on the register? Directline said they wouldn't insure it unless it was. I didn't ask Kwikfit or Rac if it made any difference as I put it under any other mod's on line.
