Just what the topic stated. I need to do about 20 psi, wouldn't the hondata adjust for that, i know you don't need it for aem ems.

stock honda MAP sensor can only see about 11psi with hondata before it throws a CEL. for greater than 11psi, you'll need to upgrade to a 3 bar.

yes sir you need 3 bar precision turbo has them.

grndcont

corect. if you boost above 11.4 psi (with the stock map sensor) the hondata wont be able to recognise it, and wont be able to add additional fuel. the ems has it's own map sensor built in to the unit.

Didn't know that.

I didn't know the ems had that either. Is there any ems users boosting above 11psi with stock map sensor?

I sure hope not, if they spent the money for an ems they should spend a little bit more and use the proper map sensor. The stock one can only see up to 11 psi period, anything above is a hack job and whats the point of having a hack setup when you spent a grand for an ecu.

Are you sure about that?

Does this MAP sensor piggyback the stock MAP? Anyone else confirm this?

Joseph Davis

OBD0 MAP = 9.25 psi
OBD1/2 MAP = 10.65 psi
Hyundaidata's claim of 11.3 psi = bullshit.


Edit: EMS does not have a built in MAP sensor. They have a preferred brand of MAP sensor they sell you, K-somethingorother, which comes in 3.5 and (I also believe) 5 bar ratings.

JDogg

the EMS has a builtin BARO sensor, its pretty useless unless you mount the ems in the air box.

aem has their own map sensors. avalible in 2, 3, 3.5 and 5 bar.

kavlivo sensors are also good stuff.

i would stay away from the gm sensor. it is not very precise. it is acurate.. it will read the same thing every time, but when it says 10psi, 90% of the time its really NOT 10psi.

Joseph Davis

I'd like to clarify;

GM 2 bar calibration is very good. For stock engines not exceeding 14.5 psi, grab one.

The GM 3 bar has a calibration within +/- 3%... which means you have to retune your engine if you ever replace one.

grndcont

sorry about that, i must of confused the baro sensor for a map. how rookie'ish of me.

Thats why I didn't know that.

CaptainMorgan

If you have a 3 bar do you still need a missing link. Will the 3 bar alone, stop the CEL? thanks

Silverbeast

3 bar will remove the need for the missing link/check valves, etc. It should clear the code.

CaptainMorgan

if i put the 3 bar gm map now with out hondata will i see problems.

Nextelbuddy

you can not run the 3 bar without hondata the stock ECU does not know how to read the 3 bar map signal its a different volatage... hondata can be programmed to read it no problem. and some people have had luck with using it with a VAFC but i think hondata is better.
