For the lat month or so i have been experienceing a hesitation while accelerating under load. If I am at 3500rpms and step on the gas it studders, goes lean, I can hear the turbo spinning but it feels like its not getting fuel. After a couple of seconds it will catch up and start to accelerate. I have switched between both of my maps and have watched the settings go up with the map sensors pressure reading in the fuel table, emanage blue. I don't have a fuel pressure gauge as of yet. I don't have any vaccum leaks that I know of. I have walbro255 so there should be fuel there. I have ran injector cleaner a couple of times to no avail. I am running out of ideas of things to check or fix. Please advise. Thanks in advance.

 

One of the short comings of the emanage blue unfortunatly (at least in my case it was). Once I got an AEM EMS, all those little annoying problems went away.

 

I guess. The map sensor is new. I have checked everything imagineable. plugs, packs, I have moved the vacuum lines around, everything.

It just ercently started. I guess I will just live with it and try and not run her to lean, and save for the AEM. Damned if its not one thing its another.

 

maybe check this? Im just throwing it out there:

the acceleration Map should fix this...


D.

 

^^ I changed the MAP sensor to a new one 3 months ago, I have used contact cleaner and it is zip tied. Its not the problem.

^ I don't have an "acceleration" map. its an additional injection map and I have switched between 2 different maps from 2 different tuners and its still giving the same hesitation.

 

turbo lag is a bitch sometimes, isn't it?

 

Its not turbo lag as I had the same problem with the emanage blue.

 

Have you change your spark plugs?

 

I had the same problem with mine and I have AEM EMS, I snapped a ring and scratched my cylinder wall. I was told to just not let off the gas and go FT anymore which is bull, but I guess its better then dumping more money in it.
