Hello everyone,
I just recently put my homemade (parted together kit) on. I'm running a log manifold, garrett 60-1, fmic, emanage with boomslang harness. Anyways according to my wide band the car is running 13.5afr half throttle or so and drops to low 12's full throttle. The car won't go passed 5.5 rpms and feels like it goes into limp mode. Could it be map? Should i get a missing link? or a rising rate pressure regulator? I'm stuck guys please help. I do have an inline fuel pump but its WAY too loud which inline would you guys recommend? thanks again.

 

Are you still using the stock injectors?

 

yeah i sure am, i figured stock injectors would hold for 8 psi

 

and the map sensor is cut off from seeing boost?

 

i dont think your getting enough fuel, thats what happend to me anyways. get bigger injectors,

 

With the stock injectors, you need to increase the fuel pressure. Or...IMO...get bigger injectors.

Which emanage Ultimate or Blue?
I know the Ultimate can clamp the MAP from seeing boost. Not sure about the Blue.

 

^ the blue clamps the map aswell. I had mine clamped as low as 2.7v and it was still seeing boost. I clamped it down to 2.6 and the p1259 issue was finally solved.
Regardless if you are only at 8psi you shouldn't have a problem at all with the stock settings as the MAP sensor can read just over 10 psi without a problem and going into any limp mode.
The MAP is 99% probably not your problem.

 

You must have a map clamp of some type if you want the engine to run into boost when using a stock PCM

 

So would you guys recommend getting a missing link? or should i just get a clamp? I'm running emanage blue. The only thing i have for that is the boomslang harness. I can rule out the emanage for the vtec setting right? By jumping the pins inside should have made the emanage aware that the car has vtec??? which was done awhile back. About the fuel I have an aeromotive inline fuel pump. Should i go with a walbro? I want something not as loud.

 

A Blue E-manage has a map clamp function built in, under the boost cut menu.


It sounds like you need to find a tuner that has e-manage experience.
