hey there everyone...great place
i have a 1.8 turbo engine that i bought a bigger turbo for and i was wondering how can i control fuelling as to be able to match the increased airflow?
thanks

 

first off what turbo did you get? i assume you have an a4? i would post in the a4 section you will get lots more hits.
you need to be able to tune your car. using a chip or some kind of custom tune.

 

its a to4e....the engine is in a seat toledo....i was thinking apexi safc...what do u think?

 

i ran a s-afc with my t3t4 in a 1.8. only problem was i couldnt controlle timing. also it was hard to get good data logs becuase the way my s-afc was set up it messed up the maf readings so i took it out and chiped the car with a custom tune. it ran a million times better

 

i have a mega squirt ...but i dont want to pull the engines original harness apart...i was thinking of getting another set of injectors and have megasquirt run those alone... i would machine extra injector bosses into the manifold. my only problem would be the timing...what do u think of this set up though ?

 

is there any one that makes a chip, tune or flash for your car. becuase thats the best thing. you get fuel, boost and timing. this extra injectors seems to much and will cause more problems with trying to get 8 injectors to work togeather using 2 different programs

 

yeah i know what u r saying...how much boost can i run before i need to alter the ignition maps....assuming i can set the A/F ratio right.i know tuning the extra 4 injectors would be hard ...i want to give it a try...i am worried about the timing though..i know the engine has 2 knock sensors but i know theres a limit as to how much timing they can pull...how much timing do chip manufacturers alter the timing?

 

i dont know how much boost you can run before you need to change timing. also i dont know the timing maps of chips

 

so i can send my ecu to a tuner and they can chip it to run the to4e and larger injectors.....boost, fuel and timing

 

yup. i used mika software with a liewicks tune from ATP
