i hav hondata s300 and innovative lc2 wideband on a lsvtec ,p72 ecu, 440cc inj, fuel press 40 psi, and intake header and exhaust. my AF ratio gauge is in the 10s and im new to using hondata ..what do i change to put my ratio in the 14s? or am i a lost cause and should take it to a tuner? also i hooked up the wideband analog output to the hondata analog input 0 red wire but in Smanager analog 0 says 0 volt

 

Honestly, if you are asking such a basic question you REALLY should consider just taking it to a tuner. I would be willing to bet you did not set up your basemap right at all. I do not recommend running your car at all for fear of washing the cylinder walls with fuel. Also, your fuel pressure is kind of low as well. Bump it up a few PSI as some injectors will struggle below 40 psi.

You should really read Hondata's help file. This can be found in SManager under the help tab or online by going to:

http://www.hondata.com/help/smanager/index.html

 

yea i have no idea what im doing ...i wanted to get it drivable to take it to tuner ..thnx

 

call your tuner and ask him to send you a basemap to drive to his shop.

 

As mentioned by others your ecu must be tuned with a calibration specifically for your setup. The smanager help file is a good start.

If you do not have any hondata tuners in your area & you want a jump start or remote assistance, we offer both custom basemap files & remote e-tunes via our website http://phearable.net/tuning-software-en/

 

I respect anyone trying to learn how to tune their Ecu. Open up the Help file in the Smanager and read, read, read.

 

check out pgmfi.org theres so much info to read it will take you a year to do it if you read every day

read about it
dont mess with ignition timing at all

first adjust for new injector size
then increase the fuel multiplier by 1 every time and drive around to see where you at.

once you are around 13-14 afr everywhere it should be safe to drive it without hitting vtec. disable vtec until you get to dyno that way you dont accidentally "engage" and lean it out. set the vtec point to 8000 rpm that way it doesnt engage at all


you also have to calibrate your wideband so it shows same afr in hondata as it shows on the gauge.

start reading basics on pgmfi , here ,hondata.com, xenocron.com,hrtuning(neptune) also has good reads, and other forums as well

 

You wouldn't change the multiplier but rather the injector sizing, but there is a fuel trim option if you need it I suppose. I prefer to do the math before hand so I am not guessing.

You don't have to change VTEC engagement points or fiddle around with all that. All that needs to be done is simply uncheck the "VTEC Enabled" box. On a side note to this you should also set the rev limit to around 6k RPM as you will trash the rockers if you are revving out to redline with VTEC disabled.

Finally, if you are using offsets to "correct" your O2 display then you didn't install it correctly to begin with...

 

if you using d14 input. neptune doesnt have innovative wideband in options i have to add it and modify the mtx-l output to be within d14 limits. 3.67 volts instead of 5 volts.

 

read the manual in my sig. the layout is different in crome, but the concepts are exactly the same.

 

OP just get one of the guys E tune for you and then go to a local shop to dyno tune


few people here do it i belive xenocron ddtech and some others

 

I may be wrong but I believe the Hondata analog inputs are not "seen" by the ECU. In other words you can't use a wideband input into an analog input if you want the ECU to use that signal for closed loop. <- Just an FYI in case you don't know.

I would load up a stock B series calibration and just change the injector size. That should be good enough to get you to your tuner.

 

You are wrong, ther are 4 analog inputs that the ECU can see as they are inputs directly into the ECU: http://www.hondata.com/help/smanager...htsub=wideband

 

I thought the analog 0-7 on V2 were not seen by the ECU. I'm sure I have seen you mention this before when people ask about hooking up wideband to these inputs.

Since OP specifically mentioned analog 0 I'm assuming he means the 8 additional inputs with V2 and not the other analog inputs.

Maybe I'm wrong and I misunderstood what you said.

 

If you really just can't figure out how it works, if you have wifi and remote desktop enabled I can guide you through it. For a nominal fee of course.
