2.0 8V Turbo Problem

[aarontrophy 26]

Hi guys

 

I have a 205 Gti running Omex 600 2.0 8v turbo engine. I recently changed the turbo and now when it's running its hesitates when I throttle it hard but if I throttle slowly it's ok?

 

Would this be a issue to do with my map need altering ?

 

Hope you guys understand my problem and can help cheers

get a laptop plugged in and check the throttle pot readings.

not enough boost/air would be my guess can you adjust the arm?

Did you swap it for the same turbo as you took off? or was it different?

[aarontrophy 26]

Different turbo

that may be your problem, what turbo was on the engine and what did you change it to?

[aarontrophy 26]

Standard 1 to hybrid

so the engine (which used to know how much air and thus how much fuel to give) has been modified to a vast extent that its getting either too little fuel for the air pressure, or too much for too little air volume. It wont work 100% without being remapped.

can you not see what im getting at, like DCC's comment, you have put a larger volunm turbo on which will most likly make your engine run lean, you need a remap! thats your problem.

What they say and maybe colder sparkplugs too.
