Rep Power: 281

After i turned my car up to 15 psi and got it retuned, the map has been doing some funny things. At first I threw 2 codes...one for baro sensor internal circuit failure and the possible causes are internal ecu failure and the other code was map sensor signal lower then expected. Niether of these codes really made any sense and the map should have been reading high. I then set my boost voltage clamp to 4.95 and I ended up with 4 codes. I now have map sensor seeing to hight of voltage and too low. Im also throwing 2 baro sensor circuit codes. The car randomly cuts out under slight accel but runs just fine at WOT but I did notice after I cleared the codes at work today on the ride home the car felt a bit faster and I havent had the codes come back yet after I reset the voltage clamp as well. Anyone else run into this sort of problem on emanage? Im about to buy a new map and possibly a missing link.

i have a turbo in my civic and i had map problems in the beginning as well..i went the expensive route and built a one of kind prototype fuel system..its the only one in southern california...i also have the emanage and i had that **** tuned like a ****..you can buy the missing link but if your boosting at 15 pounds i dont think it will work..thru my expieriance...i boost at 20 lbs but i built my engine up and putting out 420 to the wheels..i also replaced the turbo obviously..lemme know wut u think

wtf are you talking about man, I dont think you even know what a map sensor does....

Josh, This is what happens when you run high boost and dont have your map voltage clamp set properly. Theres to big of a voltage difference between your map sensor and the baro sensor (atmosphere pressure).

what do you suggest i set the voltage clamp for then?

See post #3 and #5

Since im sure DEZOD will see this and disagree with me, ill provide some proof.

(Of course there are a few factors that will cause your numbers to be slightly different from mine)

My car is able to push 7.2 PSI before it will throw the code for the map sensor high voltage. At 7.2 PSI the actual voltage seen at the map sensor is 4.03 volts. With the emanage injector correction feature it drops the voltage to 2.93 volts. Thats THE MAX boost i can run without the clamp activated.
Peak Values in the small black box........................


Lets clear some myths.............

Even at 7 PSI the map itself isnt seeing anything thing NEAR 5 volts, and thats BEFORE the injector correction! SO in order for the emanage to put clamp at 5 volts you would clearly have to be running 20 PSI+, remember the emanage sends the signal to the ECU, it doesnt come directly from the map.
Like i said in the previous post

If you think that clamping at 2.93 volts will max out the injectors look here........


7.2 PSI, 64% duty cycle, Map sensor clamped at 2.93 volts, A/f ratio at 11:9 Doesnt look anywhere near maxed to me

so if i reduce the clamp to 2.9 volts do I have to go get retuned again?

Is that off of the E-01? Is that 11.9:1 anywhere in the data? Off of a wideband? Furthermore, these RSX injectors don't like to be pushed more than 85% duty, therefore if you are at a mere 7 PSI, and at 64% duty...I was at 8.5 PSI on a T3 Super 60 and the injectors would not add anymore fuel while tuning.

BTW, Page 21 of the support tool manual proves my comment previously.



Read the 2nd bullet.

That is all. Asta!

I would recommend it.

none of it really makes sense to me still. I dont even have rsx injectors I just want to know what voltage I have to set the clamp to so that my car will stop stalling when driving and stop throwing the code.

Are you saying your running 15 PSI with stock injectors?

I have srt4 527

The only thing that helped me from throwing those map sensor codes was the missing link and then later on getting ems.

with the ems u dont even need a missing link. bc boost is not a problem for the ems its like it WAS MEANT TO BE THERE
