Re: part throttle hesitation

No you don't need to connect it to the LPG ECU, not even during the initial calibration stage... but if you can't connect to the car's OBD with a scan tool to see lambda readings then connecting to lambda can be useful if only because it allows you to confirm the mixture is correct when the petrol E...

Re: part throttle hesitation

Whatever different injectors you fit you'll have to re-calibrate the system. You'd probably need to recalibrate it anyway even if you rebuild your injectors or fit new same model injectors.. particularly if certain supposed self tuning features have been left enabled in your Qbox ECU settings (conti...

Re: Q on magic jet injectors

No probs.

Also watch gas and reducer temps, cold gas can cause injector rubbers to fail prematurely.

Re: part throttle hesitation

Plenty ideas! It's important to get point of gas entry close to inlet ports on most installs but this is particularly important on these engines and even more so on the versions with VVT. On VVT versions I fit singular injectors almost directly onto directional manifold nozzles (pipe between manifol...

Re: Q on magic jet injectors

The end stop rubbers are there for a purpose which is to act as the stop which prevents plungers opening further and probably also prevents clatter and bounce during the opening stage, if you remove stop rubbers the plungers may open wider and perhaps to a different extent on each pulse (or differen...

Re: Tank expiry date

There are plenty vehicles around with tanks much older than 10 years. As long as the tank isn't rusting through it isn't a problem, it looks like your tank is a 30deg toroidal which implies it will be fitted internally where it is unlikely to rust? They don't rust inside, they don't suffer metal fat...

Re: Petrol fuel pump when on gas??

Incorrect polarity plug on looms were often fitted on P38 mixer system installs because P38 petrol injectors are wired with opposite polarity to the usual Bosch standard, this still works to turn off petrol injectors because with opposite polarity the emulator disconnects injector positive feed inst...

Re: LPG Service / fix Manchester

It will originally have been fitted with an 8 pin Molex type connector, likely the pins in that corroded. What type of serial connector does it have now (most likely another Molex or the more recent 4 pin Superseal type)? AEB make the electronics for Romano, AEB Molex lead pinout is the same as the ...

The brand(s) of under bonnet system components won't affect the tank filling and, at this stage, won't affect advice on attempting diagnosis of the starting problem (there aren't many things to check without...

Re: Petrol fuel pump when on gas??

I couldn't remember if Gems detects disconnected injectors but did know that there are no consequences if they do (doesn't switch to open loop or prevent ltft's shifting etc). Seen plenty Gems without an emulator, just a relay (or two, one for each bank) to disconnect the positive feeds to each bank...

Re: Petrol fuel pump when on gas??

Most single point controllers feature an output that can be used to control such petrol pump relay (yellow wire or wires on AEB stuff). Most can be set to delay switching off the petrol pump during LPG priming time for a programmable amount of time. Similarly most injector emulators such as Pitagora...

Re: LPG Service / fix Manchester

Not all pumps do a hard shut-off, some continue trying to pump gas into the tank when the float/fill shut off mechanism correctly tries to prevent it.. The float/fill shut off mechanisms don't totally shut off incoming gas but severely slow it, so on this kind of pump it can be normal for the fill n...

Re: LPG mileage

I believe if a factory fitted Transit has twin tanks they will be joined by large diameter welded steel connecting pipes and only have one valve set. There is another potential reason that might cause it to seem the gas had ran out when it hadn't... If the system switches back to petrol because it d...

Re: LPG service

If just doing preventative maintenance (filters) you could buy and fit them yourself. If there's a problem of any sort running on LPG with a Koltec system do a bit of research and see who's managed to diagnose and fix them before. A lot of installers will just go through the motions with these syste...

Re: No lights on switch P38 4.0 AEB175

Yeh Bri the wiring is the same on all the AEB175 systems. The only differences between all of them are brand specific software must be used and there are slightly different options in software, nothing to affect wiring. Just to clarify... Not even the red light comes on the switch when the ignition ...

Re: No lights on switch P38 4.0 AEB175

AEB175s can use a reducer temp sensor (to allow automatic switching to gas when the reducer has warmed up a bit) but a reducer temp sensor is very seldom fitted on this type of system. I use the term 'configured' below, by which I mean options that have been set in the AEB175 using a laptop, softwar...

Re: LPG switchover problem

Try this (copied from what I said above)... You can attempt to start on gas by holding the switch button in while cranking the engine, if you do that does the engine run (or try to run)? Can you hear the petrol pump running? You might need someone to turn the ignition on and perhaps crank the engine...
