Hi!

I'm new to this ECU tuning stuff, so please, take a little time and help me out. My car is almost stock, just a modifed exhaust and i plan to go N2O in the near future.

I purchased a PRA ECU with K-Pro from a local guy who claims that he's a K-Series specialist. At least he own a Civic Type R with JRSC tuned on K-Pro.

He installed the ECU and tuned the car. He took the car for a ride, around 30 minutes, did this and that (things i don't know or understand - he poke around on his laptop) and finally he told me the engine has now good 10hp more than before.

He handed me out a file which should contain my tune.
Please can you take a look on the tune.

I'm not a expert nor that i've any knowledge about this tuning things, but i wonder how he can tune the engine in around 30minutes when other tuners need good 4 hours to tune a B-series, with tools and a dyno.

And a other questions, too. When i do a back-to-back test on the dyno, the stock ECU vs. the modified K-Pro ECU. Will both have the full power as soon i plug the ECU in and do the dyno run? Or does the ECU need time to learn to get it's full power? The guy mentionend above told that i get the full power after around 1000km of driving?!

Thank you for you help,
Roman

PS: If this is in the wrong forum, please move to the right one.

he could given more advance on the ignition.
dont know about the fuel cuz we'll need your logdata.
but the cam angles are definatly wrong!
i doubt you'll get more power than the stock ecu with this setup !

He's not tuned your car if he gave you a PRA ECU as it's narrow band so he wouldn't know what your fuel ratio is.

You'd need to take it to a dyno.

Thank you for your replies.

I spend all my free time reading about KPRO to understand the basic.
I looked at the tunes which came with KPRO and noticed that the second igniton tables looks completly different from them in my file. It looks flipped upside down?
What do you think about this?

Yes, i plan to go to the dyno.
The stock ECU is a PRA, too.
I want to test both ECUs, the stock one which was installed in the car befor i bought the Hondata ECU and the KPRO tuned one. Can i just change the two ECUs on the Dyno? Will the ECUs work immediatly or need they a time (or 1000km) to work or make full power?

Thank you,
Roman

ECU's work in a few minutes (they need that time to learn idle parameters only not to make full power.) Otherwise tuners would be driving cars for 1000km after each change.

Just make sure that your intake cools down, it gets very hot if you idle your car for 15 minutes (switching the ignition off doesn't help, the air flow cools the intake down.) and your transmission oil is warm enough.

Install a Hondata Heat Shield Gaset if you can. It is going to keep your intake cooler.

I read these from some post here...

If you don't have a wideband controller, upload a suitable calibration (since you have a stock engine you can use one of the calibrations which come with the KManager) or you may damage your engine if you go lean or damage your O2 sensors if you go too rich.

Good luck.
