Re: MPFI conversion DONE!!! with a catch....
 

I started the car and run it it is ok (bear in mind I don't get to drive it as my exhaust manifold is off!!!!) As I am progressing to the next stage for the turbo project. However it doesn't throw anymore error code.

I know that if your fuel system is still pressurised you won't hear the fuel pump whin and relay click noise... but I think the CEL on the dashboard should still comes on then goes off though?

OK, becouse if the MAP and the PA don't have the same scaling, you will not get any error codes, it will just think you are at the top of a mountain, instead of right next to the sea..

yeah, you might be right about that one. I don't remember..

Re: MPFI conversion DONE!!! with a catch....
 

yep there is a potential scaling problem until we can compare the spec of each sensor to tell for sure... Let us know how you gets on once you tried it if the same sympton occurs. If you can post up a picture of the PA sensor when you recieve it would be cool too, as I may try to get one as well and see if that problem disappears. would be interesting to know if the MAP and the PA both uses the same type of plugs? If it is would be handy just unplug the MAP and plug in the PA sensor.

yes, i'lll let you know how i goes. Hopefully i'll get time to mount in the MAP tonight, and i will probably get the PA at the end of the week ("next" week)..

do you know where I can find the ignition timing adjusment connector on the civic lsi? I bet they are at the same location as on obd-1 92-95 civics, but I don't seem to find anything about it in the helms manual..

Here, 88-89 were forward of the driver's shock tower, and 90-00 or so were all above the ECU in the passenger's side kickpanel.

thank you JD. hope i'll find a connection with the right colours..

I did not get time to try out the MAP sensor yesterday. Maybee tonight...

Re: MPFI conversion DONE!!! with a catch....
 

Cool, let us know how you get on :) Good luck!

Re: MPFI conversion DONE!!! with a catch....
 

what about 92--> obd-1 civics? do they use the service connector to adjust the ignition timing?
still can't find it in the helms manual...

Re: MPFI conversion DONE!!! with a catch....
 

i believe so.

Re: MPFI conversion DONE!!! with a catch....
 

I've yet to see the check engine connector effect timing in any way. As long as idle is below 900 rpms, you are good to go.
