Ok, this is what I have now. I have a 12:1 fmu and running 10-15lbs. I need to know if I still need/can use the fmu or should I just sell it along with the missing link? Any help will be good thanks :bbb:

 

judging by the thread title you have the hondata unit. If this is the case then sell the 12:1 as the hondata uses a 1:1 (oem for most if not all hondas) fpr. and the missing link is just as useless, if your running more than 11 psi get a gm 3bar map sensor, 87 chevy s-10 according to the dealership.

 

So just get one off of one of those trucks and slap it on?

 

Not so easy. Go to hondata.com and look at the wiring info for the 3 bar install. Ditch the FMU and missing link as DJ said. Get the hondata unit and a 1:1 FP.

 

the install is fairly easy. I found a spot on my firewall right near the stock map and mounted it with 2 sheet metal screws and some loctite. I left the stock map and plug intact (unplugged the stock map) and went a few inches down the wire to solder onto with the gm 3bar. just incase I need to go to stock, its there. plus it would have been more hassle than its woth to take off the stock map.

once the hardware is done just reburn the eprom for the 3bar option turned on and your set.

 

definitely ditch the fmu and get a 3 bar map

 

ok so i am gonna put the bypass and fmu up for sale, go to gm and get that map sensor. After that map sensor is installed reburn the chip. Now, when I do this will i get a check engine light until i ge it tuned? thanks
