I replaced the factory fit system on a Transit with a new OMVL Piro system last Sunday...
Owner had already spent loads on the factory system trying to fix it himself and taking it elsewhere, he was getting more than a but fed up of it! I only did a few checks on the factory system, which was working OK when I checked it (sods law), but the owner still asked me to take it all off and put a new system on without doing a longer diagnostic!
Had the Piro in stock because I bought it with the thought of playing about with compensated mode on a suitable vehicle, never thought I'd end up fitting it to a Transit, might seem a strange choice of ECU but I was out of stock of other 4 cyl systems on the Sunday. Still, nothing wrong with fitting Piro on a Transit and the van runs great now.
I've repaired scores of factory fit systems on Transits, Vauxhalls, Citroens, Volvos etc (Necam Koltec / Tartarini Etagas / Landirenzo IG systems etc) but for every five I've fixed I've probably replaced one with an aftermarket system.
Problem with the factory systems is the expensive and outdated parts, some of which are now in short supply, and the prospect of another part failing soon after any repairs to one part: Rebuild or replace the reducer (a rebuild isn't a guaranteed fix depending on the problem and is time consuming on the Koltec reducer)? Rebuild or replace metering units (broken stepper motor or plunger worn out / broken)? Emulation black box problem? Relays in dash problem? Fix an issue and it's likely another problem will occur that might cost a few bob to sort. The pulsed injection factory systems are even worse than the metering unit versions with one injector costing more than a full set of 4 aftermarket injectors / ECU's and emulator boxes being a common problem on them too. If there's much else besides reducer pressure being wrong it can be a better idea to replace the whole system than mess about swapping expensive factory system parts...
You know a customer is pulling your leg when they tell you all was working well with the gas system just the other day... Then you take a look and the reducer has been removed and replaced with a shunting water pipe. You ask if they've removed any parts or if anyone else has taken a look at the vehicle recently, they answer no to both.... Some customers think that by kidding you all was well just the other day you'll somehow be able to magic an inexpensive cure
Like the guy who bought a car at auction with a gas filler mounted in the wing and gas switch on the dash - then came to me saying his gas system was working well the other day but now the switch doesn't light, it might just be the fuse mate. On closer inspection the whole gas system, including tank, minus the switch and filler, had been removed
