brief history.
this is my first post and also my second honda accord. my first accord was a cb7 with h22 swap (i bought it that way). sold it to my cousin it was his first 5 speed he got drunk and totalled it....what a noob.

i had a 1993 nissan sentra SE 1.6 turbo 10-15psi(not the se-r). i built it myself with my goodfriend. had it for 3 years turbo and like 5 years N/A. i sold the car cuz i needed a 4 door for my daughter. Well now i just bought a cd7 5 speed and im eager to boost it. (cuz theres nothing like the feeling of boost )

im not a noob in the world of boost but i am a noob in honda tuning. ive been looking around and searching i know what i need or at least i think i know. i know i dont want nothing crazy 10psi the most also the car will be used for daily driving.

i need info on fuel management and ecu. so far as for fuel im going to get 440cc blue top injectors, walbro 255hp fuel pump. i also need to know what psi should the fuel be i dont want to put everything and lean out and fry up a piston ring or worse.

as for ecu i know you can do a chipped one like p70s or something like that. I wanna go with something from hondata but in thier website it says the s200 program is discontinued =( what i dont want to use is a afc hack

what are compatible ecus for my motor and does anyone suggest any programs proven to work well with a stock bottom end. also do these programs have fuel cut-off so you wont blow the motor?

like i said i dont want anything crazy just something i can have fun in and be reliable. i useto beat on my sentra everyday and had no issues whatsoever!

thanks for reading and i hope to be boosting soon.

 

Who is going to be tuning your car? There are a few more things required aside from an ECU if you are going to do it yourself.

If your going Hondata the S300 is the way to go. Check out their website, it lists the compatible ECUs.

 

i was looking around the web and found this website jk tuning... im not sure which one to get this one
http://www.j-k-tuning.com/chipped-ob...ess-p-301.html

or this one
http://www.j-k-tuning.com/chipped-p06-ecu-p-293.html

ive seen the hondata website and they show these ecus P74,P75,P06,PR4,P28,P30,P72,P61. then the website jktuning says s300 ready so then i would have to buy the s300 separate? all i want is something i can plug and play and not have to worry about it. i know after everything is said and done there will be other issues i just dont want it to be ecu issues.

i keep seeing the word basemap, im not sure about. does that mean your setup or what?
aside from other things i think all i need is a better map sensor from what im reading around the web and posts.
i think i got everything else pretty much covered. what else could i be missing aside from the obvious

 

Yes. When an ECU chipping company says S300 ready. You still have to purchase and install the S300 unit.

There is no real plug and play, as in plug in and drive away, tuning solution. Any standalone EMS or chipped OBD1 ECU requires tuning.

A base map is just a base tune that you use to get your engine started and get you to a tuner. Specially if you are boosting the engine. It is basically a file that is created to run your engine. It is saved onto a chip that is placed inside the ECU.

If you are planning on tuning your car you should be looking more into a complete tuning kit. Come with pretty much everything, all you need is the laptop and a dyno.

This eCtune kit requires you to Add what options you want. You need to choose something from all the drop down menus if you want to tune this car yourself.

http://www.xenocron.com/ectune-pro-a...dle-p-471.html

• Add boost controller (What type of boost controller are you going to be using?)

• Add chipped ECU (Need one of these if you don't already have one)

• Add conversion harness (What year is your car? 94-95 OBD1 doesn't need a conv. harness. 96-97 OBD2A, requires a conv. harness.)

• Add MAP sensor (I suggest a GM 3 bar for boosted engines, even if your only going to 10psi. The OEM MAP will read 10psi. However, it would be at the end of it's limits. It's always better to have some extra room when tuning)

• Add wideband Kit (You definitely need a wide band O2 if you plan on tuning yourself. MTX-L would be my choice. Unless you want a gauge, then I would suggest the DB red/blue & LC-1)

 

thanks for all your info

well im not going to tune my motor, ill take it somewhere and get it done professionally.
so then ill ill get a chipped ecu take it to a shop have them tune it for me then i wouldnt have to bother with a s300. maybe ill look into it in the future maybe for the features it has but i dont plan to race anyway its just to drive.

as for the map sensor im planning on getting a 2.5 bar one. i doubt ill need the 3 bar.

of course a boost controller will be in my plans as well as wideband, oil pressure gauge, boost gauge, spark plugs and everything else ill need to run boost.

i wanna delete the egr and i looked at the egr delete thread but no pics but im pretty sure i can figure out what to do just by reading.

so then as long as i purchase a chipped ecu with the basemap that i want take it to a shop and get it tuned then i should be good from there...¿correct? (its easier said than done)

 

Correct, A Chipped ECU and base map for the stock engine. I would leave boosting your engine out of the equation until you get to the tuners shop.

Best advice would be to find a tuner first. Talk to them about your project and it's goals. That way they should be able to tell you what is needed to be done before you get to his shop. You may be able to get a deal on a complete tuning package from them??????

 

Whoah whoah whoah are you saying that i cant install everything first, get a basemap for my set-up THEN go to get it tuned? if i get a chipped ecu for my stock motor, then would i have to change the chip for my set-up i.e. injector size or will the stock set-up be compatible after i boost? I will go speak to a tuning shop but im a little confused as to why get a ecu for my stock settings if they will be changed...

well i got this e-mail from the guy that i will go to, to get my ecu chipped. this is what he said
The stock Accord ECU is not programmable for boost at this time.

You will need a chipped P06 ECU for this engine setup.
The ECU you would need is listed here. They are in stock and ready to ship out.

http://www.j-k-tuning.com/chipped-p06-ecu-p-293.html

It asks for a basemap engine size, turbo, injector size, fuel pump, cam.



nissan ecu is very different for my set-up on my sentra (sorry for being a little off topic) i just told the company my motor, tranny, injector, maf type and turbo. they made my ecu i installed everything and just plug and play simple as that everything was tuned to my specs. the only issue i had was i didnt have the correct fuel pressure after that was fixed....perfect

 

Let me rephrase that. You get a base map based on your engines setup not stock..sorry my bad. And you can get everything physically setup. What I meant was that I wouldn't add boost to it until you get to the shop and have it tuned for boost. Remove the coupler from the throttle body or tow your ar to the shop.

That being said, if the guy that is gong to be tuning your car (J-K-tuning) is OK with giving you a blind boosted basemap based on your build specs. Go for it.

It's difficult to tune your engine based on specs alone. Every engine setup is different. Sure they can get them close, they are usually a bit on the conservative side though. I.E. If you were to get it dyno tuned you will probably see a power and MPG increase.

 

MPG increase as in if I was getting 20 MPG it would increase to 30? LOL you probably meant MPG decrease...oh well yeah I'm going to see what's up. Thanks for all your input ghost the forum needs more guys like you. Well I'm still a long way from boost I just wanted to get info before anything. I still gotta completely buy everything but like I said I needed info. I didn't want to go into a build without knowledge. Once again thanks ill post pics when everything is done but it won't be anytime soon until then.....take care

 

Thanks I appreciate it.

Actually I've tuned a few boosted Civics that gained MPG after tuning. People who create base maps from blind specs never have the optimum ignition or fuel maps. They are usually very conservative, so that you don't blow your engine up, or melt it.

Only time a boosted engine should use more gas is when it's under boost. Other than that it can be very fuel efficient if tuned that way.

Having knowledge of your build before you jump in is a very good thing.

Cheers and good luck with your build. Keep us posted

 

No problem will definetly will keep you posted but like I said its no time soon

I sent him a email saying this "So if i purchase this chip and have everything installed can i turn on the motor and take it to a tune shop or how does this work? Also it says in the page that the ecu will include 4 pin header for datalogging or hondata applications. Does that mean that I can purchase a s300 and it will be compatible with the ecu?

His response was this

"This will include everything you would need to plug the ECU in and start the car up and get it to a tuner.

It will include a 4 pin header for datalogging, BUT that is not the only modification needed to install the S300 system into an OBD1 ecu.

The S300 takes a MALE header instead of a FEMALE socket. The female socket is what holds the chip and is what this ECU comes with. The S300 would not fit in this ECU.

I CAN setup an ECU to accept the S300 system, but you would have to install the S300 unit into the ECU before trying to start the car."

Oh well ill just keep it simple no s300 for me

 

The S300 is over rated!
