P28 Ecu

Hey guys and gals. There is a guy willing to sell a P28 ecu and Boomslang obd2-obd1 harness. Would this be a good idea, given my current issues involving tuning. Keep in mind, I know nothing about tuning, so any help would be greatly appreciated. Thanks

You'll need it H22 basemapped and then get it tuned very shortly to optimize your mods. If you plan on doing further modding, I'd either get it and hold onto it or just let it go and get another after you get the mods.

Wow...I think I may be getting in way over my head with all this tuning business. Im not sure where to turn from here. Im just this side of panicking about this. I just dont wanna install my cams and whatnot and have my car run like shizzle, or not at all. Cuz I heard that happens.

yeah... a p28 is from a civic, so if you're going to use it, make sure you get it mapped for a h22a. i'd get the p72 and hondata it.

oh...that would explain my inital confusion. But yea, hotrod, how would I go about doing that all. Is that something that I buy and then take to the place where I get the car tuned and they use? Or how does that all work?

hmm... the fact that you're asking the question makes me hesitant on answering it. sorry, don't mean to be an ass. just don't want to set you up on blowing your motor. so... take it to a reputable (and i can't stress that enough) tuning shop and talk to them. check their experience on honda tuning, and if they check out, use them.

you can't answer how it all works? Like I said, I have zero clue about how to do all that. None at all.

Tuning is very confusing, mostly because you hear different things from different people who assume that all 4 cylinders are the same. As different as they ( 4 cylinders ) are, they all require different ways to tune. A base map is just that, it's something that will allow your car to run without blowing up while you drive it to be dyno tuned. Your car already is tuned from the factory, but changing the way a engine is designed to work ( modification) also requires modification of the program it runs on. Think of it as upgrading to the latest operating system ( Vista or Leopard ). You shouldn't be hesitant to tune. It looks expensive at first but when you compare it to the amount of horsepower it can give you along with the security of knowing your engine is safe (safer) it's relatively cheap. You're going to buy the best suspension parts, engine parts, exterior/interior parts you can find , why not have your car run on an upgraded computer??

mm yea i think you may want to research a bit more on the basics of what tuning is generally...

i see in your sig that you have suspension and want to install cams...
i havent checked the specs much of the new pro series..maybe jsut the pro2s hehe...but i guess you know you need new retainers etc..which means this is probably a slightly more aggressive cam set up than say the crower stage 1s or 2s...

i see you are asking a few questions...:

A. is this a good deal..etc..
B. and more importantly what will i need to optimize on my mods?

answers:

A. i mean if its cheap enough sure why not? youll need it..but youd want to make sure that the p28 is a virgin ecu...so you dont run into troubles like it not workin or already having some other basemap on it thats NOT for an h22.
thats why most people try to buy them from a reputable place so if it is faulty in any way, you can get it replaced.

B. personally you seem like you just want your cams installed and the car to run at its best for wat you have...a basemap is like fuel settings for your car...you need the right one for your motor and then a real tune will modify the fuel maps etc to run at the optimal settings...if you dont want any more mods then youre probably best bet (again based on what you have now) is to grab a p72 ecu and tune with that. again, you should read up then converse with a tuner or two and get a better idea....

good luck!


ill leave you with a repost on some general "tuning" options i think are available..:

"i think of it essentially as 1. chipping vs 2. a piggy back system vs 3. an actual standalone system.

1. to me, chipping is an easier/cheaper quick "tune" you can call it...
it depends on wat you want out of your car...if you have say i/h/e and you that may be all you want, then a quick chipping to optimize you fuel management would always be a plus.

2. a piggy back system is cheaper compared to like a real stand alone system but its like an option...personally i dont think i ever want a piggy back like a vafc etc because it essentially is tricking the ecu into manipulating fuel management...and not really changing the fuel management physically..
you can manipulate the vtec engagement as well..but its not recommended if you think being in vtec all the time is the best for your motor.......in fact you can loose some power if you engage too early.

3. ah..the stand alone...is more in depth...this is really tuning your car..
you would have to get like a hondata, neptune or crome onpaired with an ecu. this is costly and you will need to bring your car to someone to get tuned/hook it up to a laptop to do it yourself... plus dyno time if you go elsewhere..

ecu wise...there are a couple of choices...
like satwilson mentioned the p72 is great since it takes care of your secondaries...but that integra gsr ecu is expensive...vs say an obd 1 p28 which is muchhh cheaper...i perfer it over the p72 because the timing with openin the iabs are still a tad off in that ecu...and i plan on usin a different intake manifold that has no secondaries...the p28 also has no egr...so you can just block it off too =]

sorry for the babble got carried away..hope something helps..
do correct me if im wrong, thanks."

Read this... then if you don't understand something, read it again, if you still don't understand read it one more time. Then if you still don't get it. Feel free to ask.
