I finally heard my fully built h23 run today and I need to get it tuned, going to get a hondata but I am not sure what computer i should used, I did i little searching and I see the p72 is popular, i believe i have the p14 now, what is my best choice and why??? I was also going to go with the s200 unit. I am pretty clueless here, so tell me what i need to know. Thanks guys.

Here the set up, h23 all motor


GE 88mm sleeves
Polished and balanced crank
Crower rods
Wiseco h22 pistons (static compression is around 11.5 to 1, dynamic 260psi)
Milled head, ported polished 3 angle grind, stainless cometec .57 headgasket
shotpeened valves, double springs, titanium retainers
Clay Smith cams (cant remember the numbers, pretty wild)
JG cam gears
Portmatched intake mani, secondaries removed
JG throttle body
B&M FPR
AEM cold air
DC cc 4-2-1
fidanza flywheels
ACT stage 2 clutch
Quife LSD
My new daily driver, let me know what you guys think, now if i can only get it to idle

 

am running a p06 with my hondata

 

does everything in the car still function as it should, anti locks, ect. What is the difference between all of the computers?

 

i noticed your setup on your engine said h23 all motor
what's wrong with the p13, if you are going all motor h23
mad props to ya
smsp or hytech header would come in handy,
if they only made it for h23's

 

H23a you use a P74 (LS)

All your options are on the hondata website.

 

yeah, i picked up the whole top end pretty cheap, and decided all motor would be a little cheaper, I plan on bringing it to englishtown on the 22nd to get some 1/4 mile times

Hondata site does not list the p13 as a usable computer

Joel- is the p74 my best choice? if so why, i am on a quest for knowledge

No idea..that's what Gude is running.

You can't use VTEC ecus if you don't have VTEC...Hondata offers a p28 configured to run non-vtec though..

 

on the Hondata site...it lists:
P74,P75,P06,PR4,P28,P30,P72,P61


But keep us informed on how you run. Your set-up sounds pretty sweeet and my hero

 

Yes definitely keep us informed of your run times.. A dyno sheet would be very fine too.

 

you can run vtec ecu, it is just disabled. i was told w/forged pistons, it is recommened that you disable the knock sensor, cause the piston make a lot more "noise" and it thinks it knocking. also the p28 doesnt have an egr, so no codes from pulling it off.


now you know that a .057 gasket is dropping your compression 1.5 points right!

 

Thanks for the support guys, I hope to get some 1/4 times for ya the 22nd and plan on doing a little dyno tuning this winter so i will be sure to post some numbers.

I am going to call hondata and see what they recommend.

Yes, i do know the the thick headgasket is knocking down compression, but the h22 pistons have a different wristpin height the the h23, so that increased compression so much that the thick gasket was needed for valve to piston clearance.

from my understanding the wrist pin is in the same spot, its the rod leanth that makes up for the stroke difference. thats why when using h22 rods inh23 you have to move the wrist pin

 

correct, the rods are a different length, but i still believe that the height from the wrist pin to the top of the piston is different, at least that is what by builder said after he talked eo wiseco

 

The compression height for an h22 is 1.22 and a h23 is 1.204

Because you cant use hondata with a p13 ecu..

well there is the answer.

Thanks for the infor on the hondata, i just got off the the phone with a dealer for hondata, he says i can use the p28 and just disable the vtec. the p72, 74, and 06 are also an option but tend to cost more as the ECU are not as popular and in more demand

 

Im using p74/75

 

I run the p75. The problem with this ECU is it disables the secondaries which actually help increase low end torque up to 5200 rpms I believe.

I never called matt back from hondata to talk to him about this since I will be running a sheetmetal intake manifold in the future. I know lee (boostedh23a1) runs a gsr ecu with the vtec disabled.

 

I have my secondaries removed anyway.

 

if your going to get a hondata, talk to 2k_teg aka kyle...he has some great prices.

 

Maybe I'm missing something, but why run H22 pistons for the increase in CR when you have to run the thicker Cometic head gasket to allow enough clearance for the H22 piston's height? Why not get H23 pistons with a 11.5:1?

BTW, nice setup.

I also have the secondaries removed from my mani, so i guess i can also run that ECU as well

I originally ordered the h22 pistons cause the different wrist pin height would give me enough valve to piston clearance to deal with the fact that the head had been milled 50 thou. But when i got the block back from GE they had milled close to 50 of the block to square it all up so i had to order the thicker head gasket. If i were to do it again I would build my own head, sleeve the block, and then figure out what pistons to buy. This was my first motor and I learned a lot, a lot of thing to do differently next time

Thanks again for the support guys

What is your total cr suppose to end up? Edit post above....

Well good luck I think your gonna be running some really high cr

-Jeff-

 

yeah, it is real high, i am guessing 11.5 or 12 static, the cams have a lot of duration which knock a lot of that down. Once the rings seal up I will post the compression numbers, I am guessing around 260psi.

I was afraid that I was going to have to put an even thicker headgasket but its running on 93 test at the moment, no knocks or pings

 

Yeah I think you gonna be upwards 12 if not more I did a little math but.... Just make sure to run 93 and get a very good Tune and then make some good power
