I'm about to dump my car in a lake. I dont know if all these problems are related to my AEM ems here is the link to that thread https://honda-tech.com/zerothread?id=1656183

Fully built b16
turbo yada,yada
255 lph walboro
AEM EMS

(1)Right now, my gas guage is waaaay off, it shows 1/4 tank when it has an almost full tank.

(2)My speedo and odometer doesnt work, I took the VSS and put it on my stock sohc and it worked fine! so its a good VSS.

I also have misc **** that doesnt work like trunk light,sunroof etc but those two mentioned above are most important

All fuses were checked, wiring harness was checked by an expert. whats causing this??

 

what other electronics devices do you have besides the EMS? and did this so-called wiring harness "expert" check all these connections with a meter? I read your other post and it seems you may be placing blame on the EMS and the manufacturer when you shouldnt be.

 

I can't help you with the rest of that, but my speedo and odo recently died in my 2000 si coupe also. After chasing a few things, someone mentioned they just die. My car still rolls into vtec, etc. I just don't have a speedo/odo and my cruise control doesn't work.

Yes he uses a multimeter, and he is very good. I have:

Greddy spec 2 EBC
Greddy TT
Digital Fuel pressure guage
Autometer boost,egt,oil pressure

thats about it for electronics. and all those work fine, but of course they would, they are all hard wired to the devices that they monitor/operate.

 

I dont know what the problem is but you have some serious electrical problems dude. Its causing all of your sensors and instruments to go haywire.

 

do you know any one that has about the same set up like yours, switch ecus and see if it works

 

take it to a different electrician and have it rechecked, I woudl suspect your so called "expert" fudged the job up. it sounds liek the wiring is way off. could be as simple as a bad ground or not connected, could be as bad as wrong wired conencted. either way, have realy expert from a SHOP look at it and pay to have it fixed, that's not the ems fault it's your wiring.

 

did you get custom wiring done?

 

wiring was from a 93 ex.

 

You have a ground problem, check ALL your grounds through out the entire car.

 

im pretty sure you installed the floater for your 255 wrong, seen it happen time and time again
