Re: MOT Fail

As some here know I recently had issues with my wj grand cherokee, the check engine light faults were appearing on gas only but whilst parked up trying to fix it two others appeared, one was the output speed sensor and the other was an abs fault, both easily cured with new sensors, its possible the ...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

There was no double relay, wires went direct but looking at the prins diagram it shows me that what goes in at no27 comes out at no26 via an internal relay or mosfet, some kind of switch anyway, but as for a bodge maybe more of a fudge to get it to work because it must have worked correctly at some ...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

One of my thoughts on the problem was the power supply to the petrol injectors from pinout no26 on the vsi ecu, it didnt appear on any diagram so I returned the wiring back to the original, this also left pinout no27 with nothing to do, no 27 was connected to the petrol ecu then linked through the v...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

2001 4.0L gc wj distributorless coil pack it is, my scan tool will go deep into the jeeps electrickery, petrol fuel trims are as one would expect, restarting after the failed switch-over is easy and it drives just fine, goes quite well actually lol, with the old IM it had six pairs of red and black ...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

Hi, yes initially the gauge in the software was going to 0 however i tried an extended crank on lpg and it showed plus minus 2.2 bar, gas is there, i have fired an injector independently several times after opening the valves and it flows to the nozzle, the jeep is fitted with coil packs fitted dire...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

I have been back out to recheck the connections, totally following the new emulator wiring instructions, I checked the pin numbers on the IM socket with the wire colours and numbers and they all correspond, bold colours to the petrol injectors, bicoloured to the petrol ecu, the other bicoloured wire...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

This just weird, everything is as it should be, gas is getting to the injectors, i fired one injector and i can hear gas going through to the inlet, half tank of gas, both valves turn on, injectors are switching/pulsing, 2.2 bar on the gauge wobbles slightly when switched over but maintains pressure...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

Re: Prins vsi on a jeep wj grand cherokee 4.0l

Yes hmmm, I knew I had done it wrong :roll: the new IM loom is quite misleading I think, writing printed on the wires basically states that all the bicoloured injector wires go to the same pins on the vsi ecu, not so according to the wiring diagrams so I swapped them to the diagram. The main lpg loo...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

I had posted again but removed them because I needed to check my wiring, treble checked and it is all correct however im troubled by pinout no26 on the main vsi ecu which is injector module command, according to the diagram that goes to the injector module only, however the loom from no26 runs to th...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

Simon, thankyou, this now makes for more understanding to me, I suspected the emulator but wasnt totally convinced, there is one x 6 box which is hard wired in, think I have a pitagora here somewhere other than that I will order a new prins one, absolutely no point in going any further until this is...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

Thanks for the info, tbh im struggling a bit understanding the workings of it and trying to decipher the vsi help but ill keep going, im sure something will suddenly drop into place, the obd2 live readings puzzle me as to why the short term fuel trims go to 0 (flatline) switching to gas, they just s...

Re: Prins vsi on a jeep wj grand cherokee 4.0l

So been reading the help info supplied with the vsi software, seems reasonably straight forward however setting the lpg system using the obd2 live data way is not working, when switched to gas the fuel trims and o2 sensor graphs flatline, can see the o2 sensor on the lpg software but I need to see t...

Re: Prins vsi

Ta for the info, think its been set to go straight to gas then, no bother as it works, struggles a tiny bit up hill under full load so im guessing a service is due, i dont think its worth buying the interface lead at those prices just for this one system, got loads of leads and a serial thingy so il...
