Hi,
after months of hard work, last week went the moment to try to start my new engine, built with the following parts: 2.3 stroker kit, GT35R, HKS 272 cams, ported head with uprated valves, Buschur intake manifold with 3" throttle body, FIC 850 cc injectors, uprated intercooler and all usual mods. For the occasion, i replaced my old Walbro TDD ecu with a D-Jetro PFC ( i just verified the version, it's the correct Evo VI/TME unit) + datalogit.
Well, here is the problem, after having changed the position of 8 and 22 wires on the pinout, and wired as read here on the forum the temp sensor, i have all the values correct on datalogit monitor page, but the engine does not start. I have just verified all connections, spark plugs have tension, fuel arrives from the injectors, but it seems there are other problems, at half throttle, trying to start, it seems to try to start, but nothing. I had also the suspect that with the previous Ecu there was some modifications on the original wiring, but the person who made the work assured me that nothing had been changed on it.
Could somebody help me, any ideas? And even, if possible, could somebody who has a setup similar to mine send me a base map, i have the suspect that the base map furnished with PFC is not proper also for only starting my engine, i tried to adequate the value for injectors, writing 65.8 instead of 100 in the proper boxes, but there is something other to do?
Take patience with my horrible english, it' s my italian guy best....

 

Hi, Giangi.

I think you had an EVO 8.
If you have an Evo 6 and the correct Power FC you don´t have to change any wire.
Try to start with stock wire position.

 

Hi Rau, happy to hear you.
I just verified, as regards temp sensor i solved translating the PFC manual, red blue of the original wiring to sensor red and black to sensor brown, and it reads correctly. As regards 8 and 22 pins, without inversion the fuel pumps don't start, it seems for a difference between RHD and LHD models, if you don't do that cable inversion you can't hear pumps start ( for a few seconds, then they stop, like with the original ecu). No, the problem has to be another, but i don't understand, at the moment.....

 

i hope this mite help

u well have to cancel the imobelizer on the car so you can run it with power FC

 

Thank you very much for the info, i just knew that link, and 8 and 22 pins, as explained on that document, have to be changed for solving the immobilizer problem, if you don't do that immobilizer does lot allow pumps to start.
I'm afraid i will have to check all wirings, perhaps the problem is that some signals has been inverted when the car used the TDD ecu, i don't know, but a big work of patience is going to be done for solving this problem...

 

Check your ignition fuse inside the car, might be out, its the red 10v top left. Hope that helps, I just ran into the same problem, everything seem to work exept that my car wouldn't start.

 

It seems you need more fuel. Try using 0.85 for the injector scaling to see if it starts then.

 

Also you may need different pim offset value. Apexi sensor usually uses 33XX or whatever is in there under Apexi option but also I've used 4000 before to have car run well.

 

Thanks for the infos.....
I just verified fuses, and everything is ok.
Tomorrow i will try with 0.85 value for injectors, it could have a sense, as after hours and hours controlling all connections i don't find anything wrong, and i will also verify the PIM voltage. Nobody with a setup similar to mine could send me a map for trying something different from original PFC one? I'm afraid that the problem could be also this, or not?
Thanks....

 

Looking at your suggestion i have a terrible suspect: in the injector values box i changed from the original 100,00 to 65,8, obtained dividing 560(original injectors value) for 850 (new injectors value). Now, following your suggestion i have to write 85,0 or 0.85? If i write 0.85 PFC automatically modifies the value in 0.9, ant there is a lot of confusion about this value, on the datalogit manual they say to use 0,XXX, but it's not logical, starting from a value 100,0, and also on the datalogit forum somebody remarked this error? What i have to do?

 

I think 100%=1 80%=0.80 60%=0.60 ....
