I have a P13, it came with my swap, my question is:

Is it worth it to chip it?

I have hooked up the secondaries through vacuum and eliminated the box, EGR is gone, knock sensor is wired up.

Is there any difference between obd-1 USDM P13 and JDM P13 that would make the JDM one a more desirable ecu?

I got a VAFC to fine tune what ever ecu route I choose to go.

Basicly if I chip a p28 i will get the same results but i wont get a cel for egr and IAB.

So what should I do? sell the p13 or chip it?

 

What sort of setup do you plan on doing?

From other posts in the past, all the chipped programs available for H series are JUNK. If you plan on doing some intense all motor setup go hondata for sure.

 

im keeping all motor for this year. probably going boost next year if i keep the car

For mods, so far its just bolt ons. I/H/E, 8.5 Lbs flywheel, and 255 walboro pump. Im not going to crack the motor open for cams until i get the car running how i want it.

If i go Hondata, i can use any obd-1 vtec ecu correct?

p08,p28,p72,p13,p30,pr3

Is it worth keeping the VAFC or just dump that and the p13, and get a hondata and a p28 (etc)

 

Depending on the hondata dealer you talk to, most can only do p28 or p72 ECU's.

P72 will allow you to keep your secondaries. Its a little more expensive and harder to find than a p28. VAFC Just "tricks" the ecu into thinking its under more/less load. hondata actually is new base maps and everything else just for your specific application. If you got the money, do hondata. you can get the s200 and also have it upgraded for boost when you decide to boost.

wurd

 

so is hondata a piggyback or a whole ecu?

I disconnected the Iab box because it was damaged when i bought the motor. I dont want cel's so i think i might go with a p28

 

As far as I know, A P13 can't be chipped... Open the case and see if there is a blank spot in the shape of a 28pin EPROM to make sure though before you spend the $$$ on a new ECU

A P72 will also allow you to retain your knock sensor... Going price on E-Bay is 200.00 - 220.00 shipped for both P28's and P72's...


The reason USDMs are better for chipping versus JDM's is that JDM's have surface mount components where the legs of the components on a USDM board go all the way thru the board and are soldered in place. Surface mount stuff sucks to solder. You have to head up the solder bead and place the component and allow it to cool...

When an ECU is chipped (Hondata, Uberdata, etc) The chip placed inside the ECU overrides the factory fuel and ignition maps, etc. So to answer the question if Hondata is a piggyback or standalone, it's technically a piggyback, but acts as a standalone. Basically, you're reprogramming your factory ECU

 

great... Thank you

cant be chipped? Really too bad my chipped P13 runs very strong......

 

Mine also runs strong got it done by Erics racing.

 

Awesome! I personally have never looked inside a P13, I just assumed something was different since that is the only ECU Hondata doesn't list on their site. That is good news, I have a friend with a P13 on an H22 in his Integra that will be happy to hear that.

 

Hondata is a piggy back, not an whole new ecu. It works much like a chip, except you can tune all the maps to your specific applicataion. Some people have good luck with ericks racing stuff, some dont. With hondata you can change your setup, go dyno it and just re tune the hondata, no big deal. if you want to boost, extra 100 bucks and you can add a boost option to your s200 application. Its up to you

 

I just did an H22a swap and don't have my secondaries wired. With the p13 i have a CEL come on. I also have a mugen chipped p28 and the car runs smooth but lacks the power.

I was considering having my car wired up properly to run the p13 but don't know if that's the way to go. Maybe it's better to send the p28 to hondata.
Any suggestions?

 

have you ever seen anyone post I HATE MY HONDATA!!! ? nope. i would recommend it

 

P28 all the way! Allmotormark chip

 

A piggyback is a unit that modifies the stock sensor inputs or the outputs of the stock ecu. Hondata is a fully programmable device. Hondata is NOT a piggyback.
