Kpro fitted now rev hunting bewteen idle and 200p rpm

[Lynchdc5]

Just had a kpro fitted today and a reflash map installed on my dc5.

Now the car is rev hunting . Is there anyway i can fix this on kpro. Im new to kpro so will need to be explained to me😂

My mods are kpro. Aem v2. Rbc. Dc sports manifold and fujitsubo cat back.

What is a reflash? If you've not had it mapped properly then that's probably your issue right there. Who mapped it for you?

 

[Lynchdc5]

Its just a map that hondata provide that is safe for every car to run. This fella is a proper hondata dealer.

Title should read 2000 rpm not 200

 

[Lynchdc5]

Kpro is throwing up fault code Code P0452 is defined as a Evaporative Control System Pressure Sensor Low Input

As your fella is a proper hondata dealer, why not just take it back to him to sort out? That's what I'd do (assuming problem wasn't there before hand).

Did you replace the intake/throttle body before placing the KPro?

Yes i fitted an rbc with a standard throttle body

Then you need a proper map. Not an off the internet safe one.....

Car has now been professionally remapped and when I take it out of gear it will rev to 2k then back down to idle .

So hasn't made any difference

Are you sure you have no vacuum leak? As you said you replaced the intake manifold. If there is a vacuum leak the car hunts/bounce also to 2000 RPM.
Just use some brake cleaner and spray at the vacuum hose connections. If the car revs higher you have leakage on that part

Ok everyone the revving was back with a vaginace tonight it would just hold the revs to 2k rpm when out of gear and then once i put the car back in gear it would come down if i was in the low rpm wile in gear driving .

Really has me to the point where i dont want to drive the car .

Tryed looking for vacuum leaks and i couldnt find any. So iv now replaced tps, iacv and renewed the throttle body gaskets and its still there .

Is there anything i can do in kpro to stop it ?

 

[Crazylegs]

I know it sounds ludicrous but have you taken the car for a good spirited drive at all? I mean prolonged revs through various gears? It normally helps you know, obviously try and do it somewhere safe and not with other cars/pedestrians about. I find getting it through the gears especially 3rd and 4th really help clear any issues.

 

[Lynchdc5]

Yeah its been revved as much as a honda should be lol .

The thing that got me was the car was fine until the kpro was fitted.

 

[Crazylegs]

Strange. If you can I'd take it to a mapper and get them to look at it.

Try taking a look at the thermal idle valve on the head, these can some times get damaged when fitting the RBC.
Its a little plastic T piece to the right of the intake manifold, has a hose running to the center of the intake manifold and to the intake hose.

I think this is what makes the car rev a 2000 rpm when started from cold.

 

[Lynchdc5]

I think that valve is fine. It when the car is warm its just really has a mind of its own .

Going to strip inlet and throttle body tomorrow and re fit.
