Hi everyone (forgive my English, I'm Spanish and I use google translator) ..because not long ago I finished mounting my accord f18b2 turbo (obd2b) .. it has changed to obd1 with harness, p28 was installed with custom chip I have 550cc injectors change to 2-wire iacv, the car starts but does it very badly, and with rattles, it shows that it is out of time or the injectors do not jump where they should or the spark from the spark plugs, I do not know ... later From looking for a lot of information and to see if the p28 gave any error code, I saw that it did not give any .. I tried another chipped ecu and I got error 9 (tdc) .. As I have read and seen and my accord I have the tdc sensors , ckp in the crankshaft pulley and it is 2 pulses (tdc) and the ckp has not been able to count the teeth. in obd1 the tdc is 4 pulses and is mounted on the distributor with the ckp 24 pulses and cyp 1 pulse ... it is possible that if I change the obd2 distributor with only sensor (cyp) for an obd1 distributor with sensors (tdc, ckp, cyp ) Within it I can solve the problem of times and synchronization? thanks in advance 😃

 

I know this may sound odd, but OBD1 and OBD2 ECU's use the same tooth count for those sensors and there is should be no issue going from OBD2 to OBD1. It could be something to do with the ECU OBD conversion harness wiring or in the tune. You mention that you have a Chipped ECU, who chipped it and what did they use to tune your car?

You may want to find a local tuner that can hook a laptop up and see what is going on on the chip/tune.

 

Thank you for your quick response ghostaccord, because for weeks I have been trying to solve the problem without having to buy a distributor of the accord V, but without results and I spoke several times with the programmer and he assures me that the problem would be solved by changing distributor. But I have seen Much f23a1 turbo that is almost the same in everything to my f18b2 except that it is a 2.3cc xd..and they have the same distributor without obd2 adjustment but they worked the majority with hondata..my chip if I am not mistaken is made with chrome, since The programmer told me that the protocol for the datalogging was QD3.mo and I managed to make it work neither by cable nor bluetooth .. if I could send a video to show what the car does when you press the accelerator, it looks like a 3-cylinder tractor. .The truth is I don't know where to approach the case. I will try to find another tuner to look at my chip as well .. I have been testing the sensors that work perfectly in obd2 without errors for 1 month, looking for c continuity between all the pins of each of the aforementioned sensors and everything is correct ... each of the cables is located on the correct pin (I have reviewed all the obd2b and obd1 diagrams many times to make sure that everything is in place)
