as promised i`ve been on the car since morning, and ive checked all wiring one by one soldered every wire joint and ive insulated every soldered wire.
ive noticed that the 12v wire to the battery was not strong enough so ive used a new thick wire
now when i put the car on it only primes once not three times
the only problem i am facing is the water temp switch is reading over when i put the car on, so ill be changing it during the week.
when i swing the car :-
the RPM reading is between 396 to 257
timing is 10.6
petrol 6.96 to 8.89
Boost is 0.139 to 0.147
so it didn't catch all it did was to shoot from the exhaust as if the timing wasn't correct
you cud hear it going like its gonna catch but nothing good happened.
so im thinking of ordering the replacement 60-2 wiring and the water temp switch.
i saw the replacement wiring @ performance products SA if you guys know people you trust please tag them ill give them a ring tomorrow morning.
The red wire you refer to, is it the one on pin 8 on the wiring and is the thinner red wire of the two in the harnass? That is the switched power from ignition and size wire is adequate size. The red power wire going to pin 30 on relay is connected to the battery positive terminal and is addequate for the job.
Priming once is correct and the RPM reading is good enough during motor cranking.
What temperature sensor are you using and how is it wired to the ecu? The “over” temp reading you are getting is suggesting to me that you are having a short circuit on the temperature input. For a test, you can disconnect the temperature wire to the sensor and swing motor again. This can also give you the high fuel value of 6-8ms. Once you gave the temperature reading, you need to calibrate the temoerature values.
By saying it almost catches, I presume you have confirmed spark and fuel.
What is your fuel pressure on fuel rail, plugs dry or wet and black? Any fuel smell?
What is the main setup page values and trigger input sekections set to? Post pictures of those to check.
What is the trigger angle value on the main page? Wrong trigger angle could also prevent motor from starting.
