Car: 2000 Honda Civic EX (D16Y8 Manual Trans)
Installed:
-E-manage (pressure sensor, injector, ignition, main harness installed)
-DSM 450 CC injectors

Problem 1: After I installed the DSM 450CC injectors and programed the E-manage to hold the 450's instead of the 240's I took it for a test drive and noticed the CEL went on. It was code P1106, which is the barometric pressure sensor code. Then I found a thread that told me how to fix this code (so far it has worked) "https://honda-tech.com/zerothread?id=945417".

Problem 2: I think i have that fixed, but heres my other problem (maybe its common with the emanage and bigger injectors), when i'm in a gear and get off the gas i get a huge jerk in the car if I'm above 2000 RPM and if i get back on the gas it's another huge jerk. I know it is not my driving because i noticed this after the 450's went in. I also noticed that i cannot hold the Tach needle constant for anything above 2000 RPM. For example if I hold the Pedal at 3000 RPM it drops to about 2200 RPM and just keeps bouncing around between the 2 numbers. I didnt have this problem before i put in the injectors.

Note: i have expirenced problem 2 before and after i fixed problem 1. I am running all stock maps except the modification to fix problem 1.

Any help would be very appriciated!

Thanks
Chuck

 

Hey Chuck.

That thread ALMOST fixed the problem. But if you stand on the throttle in a tall gear at 1500 RPM, you'll get the CEL back immediately. No big deal, doesn't affect how it runs, but the stupid (smart) ECU sees that the MAP and barometric pressure sensor are different, and at that RPM at WOT they should be about the same.


For Problem 2: I had the same. When the ECU sees a big vacuum (which is exaggerated by the E-Manage) it cuts the fuel completely for emissions. If you had a O2 sensor you'd see it go full lean. There is NOTHING you can do about this, unless you tune the vacuum portion of your map to add a bunch of MAP sensor voltage at vacuum above idle speeds.. but that would introduce a whole can of worms..

My solution? Hondata. Sorry that's probably not what you wanted to hear.

Yeah, if you can live with the problems and get your full boost and partial boost tuned well, it's a pretty nice system! I like the datalogging feature, I kinda miss it with my Hondata s100b.

Another problem I had on E-Manage, is that I'd run stoichiometric at partial boost at partial throttle. At 2-3 PSI I'd see an A/F of 14.7:1... not good! Even n/a you wouldn't want to run stoichiometric at 0 PSI (relative pressure). That was with 310CC injectors, so I imagine with 450CC's it's worse. Watch out for knock when at part throttle and boosting. Another plus for hondata/uberdata.

Oh, but you and I can't pass emissions with OBD-I. I have 1.5 years to figure out that problem.

 

Yea, The only reason i went with the e-manage was to stay OBD-II. I wish I could have gone with hondata. My car should tune up decent, I'm bringing it to sound performance. I hear they are pretty good with tuning.
