k20a2 install PRA and not vtec

Yesterday I installed my new k-pro, I followed the steps as the instructions say and I loaded to test the Civic Type R tuned calibration & factory calibration with the same result.

The car works perfectly until it is time to connect the VTEC, it is not able to do so.

Error datalog attached.

I hope you can help me.

According to your datalog VTEC is activating. Without a more detailed description of the problem it is hard to know what the issue is. Has this been properly tuned on the dyno?

[kazhrd]

I've only loaded the default maps but the datalog is with the first of the picture

You cannot expect to run a stock calibration with larger injectors and forced induction. I would recommend that you talk to your tuner/dealer you purchased this from for help with a basemap until you get this tuned.

[kazhrd]

I just need to know why the vtec does not work? With the factory ECU it works perfectly. The next step is to talk to my dealer for a custom calibration

[kazhrd]

Any ideas?

[kazhrd]

Is it normal that at 5600rpm the sensor map has negative value?

[Spunkster]

Have you taken this to get properly tuned yet?

You cannot run in VTEC with the wrong sized injectors and no tuning for forced induction.

With this configuration and the factory ECU works perfectly

Attached new datalog with 4bar map sensor

Do you have a MAP relocator so that it can actually see boost?

No, I do not have it, I've made an order for that piece to see if the problem is solved, I sincerely believed that I had it but not.

[kazhrd]

The "MAP SENSOR RELOCATOR BRACKET" will be connected to the intake manifold to the position that I have highlighted in the photo?

Many thanks

I installed 360cc injectors and a map sensor relocator bracket, hondata map sensor 4bar and ECU hondata kpro v4 mounted on a PRA But I do not have .kal for this configuration . When the car reaches the gear point of the VTEC (5500rpm) cuts the injection and does not pass from there.

I need help, I'm very desperate

Looks like VTEC is working correctly, I'm guessing your fueling is way off and causing the engine to stutter.
Do you have a wideband connected so you can see the AFR? I would run it at all without one.
Just leave your car to an experienced tuner before you melt it :)

We have already made a customized map for my car, I am very happy with the result, it has won in low and medium revolutions and now it is much more progressive and aggressive.
