it comes from a 2000 civic si




obd2 a or b p28 or p30 ???? thanks for looking

 

its a P2T. lol

 

i sort of worked that one out ,

some tells me it shlould be a p28 or p30 .!?"^

 

If it was a P28 or P30, wouldn't it say so on there?

 

A P2T is a 99+ Si ECU. OBD2B

 

yes that ecu is from a 99-00 si


what do you have and why do you think you need to change?

 

that ecu you have is correct for a '99-00 si. It's a obd2b ecu. p28 ecus come from '92-95 ex/si it's obd1. i dont know about p30.

it's a 2b p2t

 

well the reason is because a tuner asked what ecu i had , he stated it should be a p28 or a p30 odb2 A or B ,
well after putting in s2 cams and s2 cam gears in the civic im getting my ride tuned-mapped using hondata,
sorry for all the noOb questions but im new to tuning stuff , can some please explain to me what is needed , can i reuse my old ecu??

Your car came from the factory with an OBD2b P2T ecu, as pictured.

People often swap these out for an OBD1 ECU because of the tuning options available. A P28 is from a 92-95 Civic EX/Si and is used on a SOHC VTEC D16z6, but people tune them to run most engines fine. The P30 is available in both OBD1 and OBD2a. It came from a Del Sol VTEC (B16) and is basically the same thing as a P28 but has a knock sensor board. You'll want an OBD1 version of that ECU if you plan to tune it. You will also need an OBD2b -&gt; OBD1 conversion harness to put either a P28 or P30 in your car.

 

thanks for the replys guy's

slurp 56 , so obd2 ecu's are not tunable ,
so i need a odb1 ecu either p28 or a p30 version and a conversion obd2b &gt; obd1 harness

my tuner want $700 for supplying all parts , install and tune , should i being paying sort of price ..??

conversion ecu $389
hondata $184
rr $250-300

The only price that looks on par (seemingly) is the hondata price of $184.

Conversion ECU - A P28 or P30 ECU should be able to be had for between $100-$150. A jumper harness is $75 from rywire.com.

RR - If this means R&R like Remove and Reinstall, then that is way overprice. If that includes the tune, then it is probably about right. Different tuners have different rates, so just compare his hourly rate with his price estimate. Also you should get dyno plots of before and after for that kind of money.

 

P28 is from a 92-95 civic EX/SI and is a OBD1 ecu. I'm assuming the reason why you tuner asked you those question is because Crome is a rom editor program and works only on obd1 ecu's, because obd2 can't be chipped. P30 is a obd1 b16 ecu. I'm assuming del sol VTEC's came with those ecus. Anyway, if you want to use Crome you have to do a obd1 conversion and then get a hold of a obd1 ecu.

 

sorry rephrase what i was supposed to say was rrt= rolling road tune $250-£$300,

my tuner only deals with hondata , why would he ask such a question ?!"$%&

so to clear one thing up then , my p2t cannot be chipped .?? and if it helps im getting a hondata s100 ,

thanks guy's ..!!

 

cannot chip obd2

you can reflash, but not even near cost effective.

Get any obd1 if you want a chip. Do not get hondata, unless you have money to spare and want the kewlness of saying " i have hondata"
Socketed ECU and a dyno tune is all youll ever need.

 

yea your ecu can be chipped.... you are muh better off getting a P28 though

 

who am i to believe THC07 says you cannot chip odb2 and EP1DEM1C says you can?!?!!

so the hondata s100 is basically a chip which is soldered on the chip board ,

so what is the s200 , the blue interface box and the s300 the plug in module , what is the difference between the the two apart from the optional extras they all have ,

and before some one tell's me to http://www.hondata.com , i already have ,

 

you can chip a OBD2 your going to throw a code though. My friend chips ECU's all day long as a business. your best bet is to use a P28 though

Why spend all the money on Hondata when you can use something cheaper and is just as efficient?

edit: you can reflash OBD2 sorry but still dont use Hondata

 

the reason of having hondata and neptune is to have i somewhat more realible, a tuner with experience is going to know how to work crome easily but if the tuner you have is some guy that was running a smog shop last week and just bought a new dyno progrman he isnt going to be efficent on crome or uber

you can NOT

 

hondata it is then !!!

thanks for the info honda-tech !!!!!

Hondata won't work on a P2T .... Hondata is only available for K-series and OBD1 ecus.

 

Any OBD2a or OBD2b (96-00 Civic, 96-01 Integra) is over priced for programming. Yes, it can be done, contact Mugen or Spoon directly for their replacement ecu at around $1000



So can it be done, yes. Is it cost effective? Not really.

 

lol thats no fair spoon and mugen are not known for their bargain deals lol

thats like saying yes motors can be build, contact spoon for their crate engine

Spoon and Mugen ECU's aren't chipped in the traditional fashion that we're used to hearing about (ie. Hondata). They're a factory reflash. The ECU comes programed with their maps just the same way a stock ecu comes programed with a stock map.

They aren't bypassed by a chip. They're completely reprogrammed.
