Hondata

Hi Everyone,

I have recently had my car tuned (remote) after installing the hondata FSU & Ethanol sensor. I thought all was fine however, after the car has warmed idel is hunting, sometimes it goes away for a moment but will return. I have let the tuner know and he said it looks like its a vac leak between the maf and turbo. I have checked and could not find anything. Is this a tune problem or there is indeed a leak? I have attached some logs

cold start idle (when the idle is fine) warmed up idle (when its hunting) and a random 2-7k pull Mods are:
Prl race maf
mishimoto intercooler & piping
mishimoto radiator
... exhaust
3" front pipe
hondata fsu
dw300c intank pump
zetronix flex fuel sensor
an6 teflon fuel lines

this is my vac setup, is this correct? Any help would be appreciated.

Thanks.

Where is the MAF located. That diagram is not clear how anything is really plumbed.

Hi Spunkster, maf is located in oem position along with everything else.

I have noticed that when the AC is on the idle will return to normal, then when AC is off it will start hunting again.

Problem has been resolved by updating flashpro and tune to current software version.
