1.6L MAP Emanage Settings

[rbuecker]

Currently running emanage on the 1.6L alpha with MAP. The rotary settings are 38A, and the fuel correction for different injectors works (set at 190 stock for now, seems to run a little rich though with 290 for correction). AFR usually about 15:1 at idle but sits more around 14 at the moment. Gas mileage still looks okay.

Problems thus far; Emanage complains about missing vtec since these are honda PR settings, but it still works (ignore red flashing light). I have an idea to get rid of it, but for now- not really an issue.

The injector harness is straight forward, just splice 4 wires into the ecm where the injector signal wires are. I'm not using the stock map sensor for any of the injector tables, I recommend using the greddy pressure sensor or a suitable replacement (see omgbossis21 for details )

I'll scan my notes and post those up as soon as I can, hoping they help someone else somehow somewhere.

I'll edit this post after ignition has been taken care of, still fighting tiny injectors right now.

All of the scans and pics will be up underhttp://hyundairacer.com/emanage
Here's the main one that I was concerned with though. This is from the ETM for 04 Accent:

can yuo remove the rev limter with the emanage ???

[omgbossis21]

Nope I dont think you can remove the rev limiter. Rub, you must have the jumpers set wrong. Your jumpers should be as followed:
JP1 - 1-2
JP2 - 1-2
JP3 - 1-2
JP4 - OPEN
JP5 - OPEN
JP6 - OPEN
JP7 - 1-2

Leaving the map signal alone is the best option, Im leaving my maf signal alone. Tuning with the optional map sensor and injector harness seems the way to go. If you are still running rich after your injector correction takes it factor, perhaps your fuel pressre is to high? What do you have it set at, after tuning the emanage i turned my fuel pressure back down to 43psi. Remember 99% of injectors are rated from 43-46psi ;-)

i'd like to avoid talking about the jumpers without stating their purpose and settings. there's far too much cruft floating around the internet without useful descriptions. people need to know why jumpers are set a certain way. for instance, i know i have vtec disabled on the board, but i'll bet you cash money that if i enable it, my flashing red light will go away. leaving the map signal alone is not an option, i am not happy with stock nor will i ever be.

I'd be willing to bet if you change the jumper to enable the vtec you would have even more flashing codes ;-) Also I wasnt thinking when I mentioned leaving the stock map signal alone, Im tuning with maf and being that mine is already maxed out adding voltage does nothing, so tuning with it is useless :lol: Im not sure on tuning with the map honestly, whole other setup than what im studying on. However ur stock map only reads vacuum to atmospheric pressure (zero) correct? Neways here is jumper settings explained if you dont already know.

Jumper settings inside the E-manage:

JP1 Ignition input pullup/pulldown select
1-2 A resistor is pulled down to ground
2-3 A resistor is pulled up the +ve rail
* Use 1-2 when the ECU's driver transistor is
connected to ground
* Use 2-3 when the ECU's driver transistor is
connected to +ve (5V or 12V will determine JP2's
setting)
Supposedly you can see the input voltage in the Main Unit Setting
Information window. If it's 0v, use 1-2. If it's 5v or more, use 2-3.

JP2 Ignition output select
1-2 Output resistor connected to +5V
2-3 Output resistor connected to +12V
* This will depend on the ECU ignitor signals output
* JP2 enables the e-manage to duplicate the amplitude
of the original signal

JP3 airflow/VTEC output select
1-2 2nd airflow meter
2-3 VTEC
* Even if you don't have a 2nd airflow meter, leave it on 1-2 for non-
VTEC applications

JP4 airflow/VTEC input select
1-2 VTEC
2-3 2nd airflow meter
* Even if you don't have a 2nd airflow meter, leave it on 2-3 for non-
VTEC applications
* On 1-2, enables pulldown resistor (for use as VTM signal). This is
required because the VTM output is inverted with the VTEC out.

JP5/JP6 Sub injector drivers
Jumper off - Disabled
1-2 - Enabled
* Only enable if you're going to control extra injectors with the E-
manage

JP7 VTEC
1-2 Non-VTEC
Jumper off - VTEC
* On 1-2, enables pullup resistor (for use as MAF output)

possibly, the error is 14 incorrect jumper setting jp4. but like a double edged sword, also means incorrect vtec signal input wiring. i could always just remove the led (or at least tape over it, or just stop thinking aboot it)

[omgbossis21]

just make sure jp4 is set at 2-3 and the problem should dissappear =-)

man you have to understand how lazy i am. you'll see an edited post a year from now about error code 14 if anything =p

[rbuecker]

you're right, we're going to have to not only clamp map/maf voltage to keep the ecu from seeing boost, but clamp the o2 sensor to keep the ecu from pulling fuel that we're adding and causing us to lean out while in close loop mode. mohd mentions enabling vtec to use the clamp "adapter" which should get rid of code 14 also. pics / docs / info to follow ..

[omgbossis21]

O yeah once i clamped my maf voltage at 5.0volts not only is my cel gone for good but it allowed me to up my boost from 7 to 9psi without problems! I was running outta fuel before at 8psi so i had to run 7 now i can do 9 just not 10. Soon to add some pulsewidth and be back to 11! Unclamped when a map/maf tries to read more than the ecu can understand the ecu goes haywire, now that sucks.
