hesitation issues (again) on my H2B swap HELP......

Hesitation (still) under loud on my H2B conversion???HELP….

Ok so as a lot of folk may know this has been going on for a few weeks as I only get Saturday to work on the car and I still have not resolved the issue(s)….

So the issue, the car feels like it has a parachute attached to the rear when accelerating be it hard acceleration or soft, the revs pick up slowly the engine noise increase but the car goes nowhere its like it is in mud???

The swap was JDM B16 to JDM H22 using B16 engine harness so nothing should have changed i.e. broken cables etc as the Sol run fine before the swap…

When the auto tech came out he read the ignition timing and it was showing out of the 15 degrees +-2 thresholds, the only time we could get it correct was sat on tick over and it went under 15? this was with the timing advanced as far as the dizzy would move?

THEN

When we drove the car with the computer attached the timing was retarding back to 0 or even a minus????
So checks performed so far:

Faults found –
o We had 2 of the injector plugs crossed 1 & 2, this is now corrected and stopped the misfires
o Spark plugs were sooty but it has been running like jobby so that was kind of expected, they have been cleaned up

Items checked –
Checked the timing belt today and it is timed correctly TDC etc so that rules that part out
• Checked the TPS that reads 0.48 closed and 4.48 WOT so nothing wrong there.
• Checked the MAP by swapping with others and no difference + the MAP on was from my Sol when it was running the B16 without issue.
• Checked the injectors and they are all ticking as they should, we do have a resister box in place so I need to double check the wiring on that.
• Changed the Dizzy
• Changed the ECU
• No CEL’s are been presented to the ECU
• It’s a new fuel filter
• Removed the Tomei adjustable fuel pressure regulator and replaced with standard and no change
• Checked vacuum hoses
• IAVC swapped no difference
• FITV checked but bypassed anyway
• EGR deleted
• Coolant bleed too many times to remember
• New thermostat
• B16 KNOCK Sensor installed as we smashed the original whilst preparing the engine
• Earths checked swapped added etc
• Fuel pump worked fine on the B16 and has not been touched
• New gaskets etc on everything when built
• New O2

Checks to do (can anyone add to these)???
• Check Knock sensor – need to know how, can the car run with this disconnected?
• Remove injectors and get those checked or if I can check them? Does anyone know how?
• Check resister box wiring and check it is functioning – is there a good how to for checking if it’s working?
• Reset the idle as it’s out with this new ECU.
• The Dizzy is not timed up correctly due to been a new one and this looks to be a pain to do as there are no timing marks on a H2B conversion does anyone know how to do the ignition timing? Can it be done live whilst plugged into the computer like the auto tech was looking at?

Guys we now need help what the fook else can be checked to try and resolve this??? Any helps tips how to guides etc?????

they have not been done by me but the previous owner did i believe however there is not suggestion of this with regards to noise from them when warm all cold, i suppose it is something to check so i will add it to the list thank-you

just checking my vacuum set up against some google pics

also check our resister box wiring and it matches the diagrams out there on google etc

This honestly sounds how @vanzeps car was before his cams were swapped. The guy he used was an x honda specialist. Was something like 3 teeth out on each cam. Sure vanzep can better explain bud.

Hummmmm just looking at the manual and do we have these vac lines correct? from looking at the manual the fuel pressure reg goes to the front facing connector on the mani we have it going to the side??

Going from memory here, but I don't think the vac lines are right. The black one should go to the throttle body and the blue one in the throttle body should be swapped around with it. I assume the plastic box on the right in the first picture should be under the inlet manifold?

Yes, it looks like you have the system that controls the IAB's connected to your fuel pressure regulator and vice versa.

See here, though you will not have the black cylinder that intersects the fuel regulator to the throttle body (its onlt on some JDM cars).

The manual has the vac routing diagrams for you to follow through.

from reading the 4th gen manual it would suggest even with the parts we have missing from the conversion that we may have had it wrong and it should be like this:

and i have had too many beers to test drive arrrr
