I have a 88 CRX HF with a H22 in it, I also have 2 bad injectors cause the engine to flood everytime i turn the ignition on. So, my question is what do you guys think about upgrading the injectors? Stock injectors push 345cc and the ones I am considering are 370cc Accel's.

How well will the injectors work on an internally stock H22 with a untouched P28 ecu? Could i get away with it until i have the funds to get it tuned?

Just wanna know some of your guys' theory on this.

 

the problem is unless the fuel map is mapped for the 370's its gonna run a lil rich because it thinks you have 240's with the stock p28 so its going to calibrate for that so if the injectors are say @ 60% duty cycle the injectors with actually be at about 144cc's where the 370's @ 60% are 220cc's its a big difference, i would recommend atleast a good base map calibrated for 370's hope it sheds some light

 

Don't use a stock P28 on an H22. Have it at least socketed/chipped with a P13 basemap. BTW, crome has that injector calibration dealy.

 

stock is 290cc...and just by two new ones to fix your problem.

 

the factory injector size has nothing to do with it, a p28 is mapped for 240's so it doesnt matter what size he has now unless it is remapped for the factory injector

i have seen stock p28 run stock h22's... not wise but oh well not everybody wants to even care

The injectors are pretty old so I would rather start out on fresh injectors. thanks for your input

Im using a stock P28 just to get it running then I'm having it socketed with a P13 base map. I could run it on the P13 i have. It will throw trouble codes since i dont have the EGR or the IAB's wired in.

I have swapped H series into EG's and used a virgin P28 and they ran strong, but tuning them for bigger injectors definatly made a difference.

So i think I'm gonna get those 370cc injectors and tune it.

What would you guys recommend for tuning? I know there is chrome, Neptune, and Hondata out there. Also, what do you think about the Innovative Wide Band?

 

I'm using a P13 right now in my H2B and have neither EGR or IAB's wired in and I am throwing no codes for either.

 

I dont unsterstand how that would work. The P13 looks for those and if it cant find them it throws trouble codes. ???

 

well the iab's on h22's are vacuum operated so it wouldnt matter no sensor for it to throw a code, on the EGR i cant answer that because everyone knows aswell as i do that egr equipped honda's are known for egr function issues and throw codes all the time its better to delete and chip it out

Correct no codes for IAB's no sensor...

I have yet to get a swapped H22A car EGR system running with no EGR code...
I have all vacuum hoses routed right and wirring and the solenoids work etc...

EGR = **** to problems...

With a P13 ecu... you should notice a lil miss kinda at like 3K rpm and that is from the EGR not being hooked up I believe or not working correctly. It's happened in 2 cars so far that I ran with the P13... EGR usually comes on when putting a load on the car such as going up a hill... usually never throws a code upon start up.

The best investment you can make on your H22A swaped vehicle I believe is the P28 ecu chipped with a tunable software such as Crome.

I would never run a stock P28 on a H22A... stock P28 designed for a lil 1.6 sohc...

370's sound good if you are going to just get it chipped with a basemap but if you were going to get it tuned by a tuner with Crome etc. I would go with 450's...

On an internally stock motor?

 

its meant for a 1600cc 105 horsepower motor, ur wanting to run a 2200cc 180HP motor with an injector 1/4 its size, and a fuel map nowhere close to being healthy for the H22, dont be a cheap *** do it right the first time so you dont have to fix what shouldve never been broken

 

i have spent so much money on this project nobody could call me a cheap ***! I hope to have the funds for 440cc's and innovative wideband O2 soon.That way i could tune it on my own, i have a couple people willing to give me their expertise on tuning considering i have never tuned a car, except for old carburated muscle cars but that **** was easy just but the frt that works the best in and your done. Does any one have a source of info as far as tuning goes? i need to get as much info as possible

 

tunning leave up to an expert! I don't even mess with it...

Someone who has experience and knows the lil tricks will get you the power you want with no flaws and done in a timely manner. Average tunning cost is around $120 hour a good tuner should be able to get you real close within an hour and half.

I have had the same tune for a while now and for me it was a wise investment. Drove it up there with a p13 runnin way rich naturally...smokin... power band was decent. Slapped a p28 in and Crome... Drove it home got on the free way and I was spinnin my tires all the way up the on ramp lol... talk about a night day difference in power band, overall drivability, and acceleration...

same day, same dyno
P13 185 whp 158 trq
P28 Crome 200 whp 168 trq

 

tune it at someone who knows how to tune. use crome. cheap and easy. has a two step. shift light. etc... awesome investment and use the P28 with crome. don't drive it with a stock p28 ecu unless you want to replace that motor soon... it will lean out like and then its goodbye motor...

good luck.

 

Cool thanks guys I still wanna learn to tune my own ride! I know a guy that said he would let me use his dyno and show me the ropes on tuning hondas. That way i could use it to tune other peoples rides and make some extra cash!

Its not gonna be free, he said about $200 just for dyno time. Ya im still pretty lucky.

 

So, I've been looking around for some 440cc injectors, and RC only hass 440cc in saturated and i need peak and hold. They(RC) carry 370cc and jump to 550cc, which is to high for my setup.

Does sombody know of a trusted company that makes 440-450cc peak and hold injectors?

Get out cheap, there is one guy on ebay that sells re conditioned and tested to be as good as new 440 DSM injectors (Blue Tops) they are peak and hold and far as I know just need to modify the O ring (enlarge a bit) . They are like $130 or so.

 

Here's a noob question, if i got 440cc's and ran it on a stock P13 what would happen? would i just run really rich or would what?

 

it will start out running rich then it will go lean..

 

what would cause it to go lean?
