Hondata

Greatings everyone,

I am a newby with ECU tuning and so Hondata.

I will attempt a S300 OBD1 in a 1999 European Honda Accord Type-R CH1 OBD2.

Stock engine H22A7 VTEC:
-2.2 Ltr
-212 BHP at 7200 rpm
-215 Nm at 6700 rpm
-Fuel 98 ron only
-Injector size 280cc

Mods on the car:
-Header
-Testpipe
-Cat-back
-Carbon Airbox.
-Hondata heatgasket

Ecu:
-P28 ecu
-OBD2 to OBD1 conversion harness

Other planned mods for OBD1 conversion:
-Rosko Racing EGR valve blockoff plate
-Rosko Racing 3 to 2wire AICV conversion plate
-OEM Honda ITR DC2 2wire AICV
-Trottlebody heater bypass
-Delete warm water pipe's on the AICV
-PLX Wideband Lambda sensor & gauge
(-Camgears if needed)

Expected problems:
-The H22A7 has a crank sensor

Can anyone help me in the right direction for the H22A7 map please?

Your feedback is much appriciated!

Anyone?

Did you find a basemap?

How did you solve the crank sensor issue?

No, nothing yet.

I had to replace my clutch so no work on the ECU done.

I did put in a PLX wideband to be ready for the S300.

And you any succes?

:D I think I'm your new best friend...

I've got a similar spec to yours

Custom SS inc decat
Skunk2 Cam gears
P28 Hondata S300
AEM UEGO wideband (D10 on ECU)
Exedy Stage 1 clutch
Fidanza 8lb flywheel

For the IACV mine was a Civic VTI (tried a DC2 and Prelude but didnt fit as well).

I will upload the map I have but consider my cams are dialled -2.5 and +2.

Last dyno the motor was making 240bhp at the fly (201 whp). The map was still lean :shock: I've done some more adjustments to low speed fuel since and the motor pulls harder now. Not had a chance for another dyno yet but hopefully into the 250s.

Have you found this site - www.accordr.org? There are a few members in the Netherlands.

Here is the map

H22A7
2198cc
With the exception of adjustable cam gears everything stock

Injector size is actaully 290cc!

Last dyno 240bhp at the fly / 201 bhp at the wheels / 180lbft torque

In no way is it perfect, I think the fuel tables still need work. Happy to receive comments if there are any S300 gods out there willing to look?

Much appriciated Sir, you are Gentleman :D

I think we have met before Doctor 8)

LOL! Ok, let me know how you get on. Any improvements in the fuel map would be much appreciated!

I most certainly will Sir !

fat2wired I just used uploaded that map and did some tuning. I removed ALOT of timing(10*), adjusted the fuel alot and tuned the vtec crossover. It's much faster at all engine loads. Compaired to the map I was running their's ALOT more timing than that one lol. At WOT at 8k it says my duty cycle is at 102% :shock: I've also never touched the timing on my other map but with your map it mad my car noticably knock. My modds...

JDM H22A
cold air intake with BPi stack/K&N filter
Euro R/type R intake manifold
Professional Products 68mm throttle body
JDM RS*R header
60mm testpipe and exhaust
MSD Blaster 2 coil, Vision plug wires and cap, NGK iridium plugs

I just worked for 7 hours. On the drive home, it amazed me how much more low load power and throttle response their was. This is rediculous.

For the timing, maybe your cam gears being dialed in different than OEM has something to do with it. I also only have an H22A instead of the H22A7, so IDK.

my friend has a completely stock H22a7, he put this map, and his car started throwing codes :S... I mean ELD, and Oxygen sensor, and his knock level was 5V...

I don't know if its the tune or if its a ground, or wrong wiring... I wana help him but don't know where to start :(

Any tips and ideas guys?

I mean a wiring diagram for the H22a7 would help me alot as I need to go over all his wiring since I don't trust wire shops here in my country (middle east, lebanon)

thank in advance...

@H22A_lude could you post the revised map after the fuel adjustments you made?

Would injector size make difference? Though if you had to ADD fuel still makes my one way off...

I have to admit the map I posted had a fair bit of knock at low rpm. I think I've fixed that now.

hey far2wired
