I am in the process of getting an ecu for my Type R, I have some god rumors that an P72 ecu chipped with either a Skunk or Jun program works well enough to make reasonable power. Although in a hondata program with P72 you can gain power but you spending alot more money. Which one would you guys recommend and WHY need help quick.


thnx

 

Why are you changing your ECU and what do you hope to accomplish?

 

all motor setup, and changing VTEC curve and redline and more POWAAAAAAAA

 

What is your current setup?

Where do you need more power?

What is your main use for the car?

 

good lord soo many ??'s......running skunk2 stage 2's, need more power on low end

How will we know how to help you if we know nothing about your car?

If you have aftermarket cams, get a standalone.

He's trying to better qualify what you want to do with the car so that you dont waste money on it. There's more to owning a car than going fast in a straight line and dumping money on mis-matched parts.

Go with a Hondata and get it tuned on a dyno for more 'pore'

 

sorry if i came off moody Ya I heard a hondata would be better, but I am i the process of purchasing a ecu through my freind. He has the p28 and p72 ObDI right now and I wanna pick it up. He also has both of the programs.

 

Those programs are fixed. You will not get the most power out of your mods this way.

 

P28 is a lot cheaper than P72 and works very well with Hondata.

question about this actually, the main difference that I can see between the 2 ECU's is the removed knock sensor for the P28.. i'm not sure how functional/effective the knock sensor is anyways, but does the hondata p72 programs make use of it?

 

With programed chips you can only get so much out of them, cause each car is different... with hondata you can tune it to your specifics, but yes you would need to put out some $$$ for the tune, but that is expected if you want to bring out the most of your car. A preprogramed chip is a quick solution, but may not be the best.. I had a prepregramed chip before till I noticed I was running lean for over a year

i only runs p28 chipped with 10 k redline and VAFC . It was more than enough for me and runs good too. i have ask dr. charles about hondata and he just told me that i do not need that thing and not even fuel system upgrade.
I have seem a lot cars with expansive ecu or brand but when it get on the dyno , tunner still need to do a lot works with the VAFC, which is really not worth the money for me. gl

since you purchasing ecu and harness, might as well get at least s100, even better s200, or purchased them used..

it will work with knock sensor..

 

re chipped p28 works well on my R..but looking at doing Hondata s200... mine runs a little rich now..but looking forward to doing the Hondata with a little dyno time...

you'd need an ecu and harness on top of that anyways no?

i guess my question is what are drawbacks of going with the cheaper p28 ecu in a car equipped with a knock sensor.. speaking of knock, i haven't seen many people talk about the j&s safeguard for a long time..

 

a base hondata map with no tuning should make as much power as chipped ecu setup.

get it tuned and you will have more power.

The quote from Matt at Hondata when I asked him about using a P28 and losing the knock sensor nd he just said, "nah, the P28 will make more power since it can't pull timing, you should be plenty safe"

Good enough for me. I ran a power FC that used the knock sensor and never had any issue with the knowck sensor.

If the tuner, and I'm not talking about dr. charles, tunes the VAFC over tuning the actual timing and fuel maps either 1.) they don't have the software to make changes(reason that you should purchase the product from the tuner, or know that the tuner can tune what you have) or 2.) the tuner is a joke.

Either the P28, or P72 can work, you just don't have the knock retard circuit(that stops working after 5,000rpm as per the Honda programming) I've used the P28 with a J&S for a 20,000 miles, numerous drag strip runs, 4 track days, and ~7 autocrosses, no issues.


More info on the J&S can be found here https://honda-tech.com/zerothread?id=207586

I say Hondata...especially with you living in the Bay Area and being able to have Lawrence at DynoSpot tune your car.

why not get the hondata , yes the chipped p72 is better thna the stock set up , but its chipped the same for our cars, or mods or whatever, but when you find out it still to orich or lean , or toom much timing or too little, then you wasted money, i like my hondata , becuas ei can change whtever i want whenever i want

hope that helps sway you

 

Often, (but not always) aftemarket chips disable the O2 sensor and run about 40% rich at part throttle.

In a typical year's driving the cost of the additional fuel used is more than the cost of having a Hondata system custom tuned.
