It has dictator on, on basically a K-jetronic setup.
Anyway tuning was really bad so stuck it on the dyno, ran through the map and gave it back to the owner , which calls me 20 minutes later, it died on the highway and he is getting it towed home.
I am baffled.
Anyway go fetch it a few days later, gets there - it starts just fine, i stick it on a trailer and take it home.
Drive it for 16 km and it dies on me. Wife fetches and it is basically flooded. I look at the dictator and it appears as if the thing thinks it is at full throttle ie. it is reading no vacuum.
I check all the hoses. find nothing funny, Check fuel pressure, set a few things on the management and suddenly it starts and runs and all is well.
I drive it for 50 km and declare everything A OK as there appears to be no issue.
Drive it to the customer which is about 55 km form me and 2 km short of his house it dies again. Same symptoms - floods the motor, when you undo two injectors it runs. add a third it runs, touch the plug to the 4th one and the motor dies, flooded.
I decide it must be the dicktator box. pull it out, drop it at the very unfriendly , don't park in the driveways, no, don't use that door people of dicktator with instructions that the stupid thing is broken and they must test it for a couple of hours. Don't hear a thing for a week and then when i phone them they declare the box to be fine. I am annoyed because cleary it ain't.
Anyway , stick it back in the car, load the tuned map back and it starts right up, runs for two minutes and dies, flooded. So by now I want to kill or burn something.
Look at the box and again it appears as if the manifold vaccuum disappears. I decide to fit tps and tune on that.
but the TPS Tb i get does not fit so I decide no there has to be some other issue. relook all the vaccum pipes. find a small broken piece on the vacuum one way valve, fix that. all seems ok, reverse it to the dyno and it dies again. Flooded. So I let out a string of swearing that has the wife, cats, dogs and neighbours fleeing for the mountians.
At this stage I fiddle the wiring and the injectors starts clicking. mmmmmmm.
so I open the wiring loom.
a) there are some exposed wires that seems to be rubbing.
B) the genius that installed the box thought hey - why do they give two wires for injectors when there are four injectors. Oh heck never mind let's just connect the whole lot together.
so now when the driver fires it has the full load of 4 injectors plus it is firing back into the other driver. This seems to make the whole box fall over.
So I changed the wiring to the right scheme, fixed the exposed ones and retuned the whole thing again as it now actually works like it should.
Took it for a 80 km drive last night and all was well. Came to work with it and will drop this afternoon.
So anyway - if you decide to install a management system - please read and understand the wiring diagrams and follow the instructions as the people that build it actually have a clue of how they should work, not how you think is OK as that might save other people a whole lot of hassle.
check out this beautifull wiring. The cause of HUGE frustration......I suppose I must go appologise to the very friendly lot at dicktator........
