Hondata

Ok well that was fun making a new map for this tune. lol I will be getting the car to the dyno hopefully on wed, so will post numbers and map when done for anyone else to use.

individual throttle body's. they tune differant then a normal tune. I have to use the TPS not the MAP.

Damn yea you are rich. lol Well good luck. Also yea the stock H22 map was screwing up this prelude the other day. Doing an ITB tune on it tomorrow.

Can you post a data log of 3erd gear? is it only under load? always?

I would go with the 650cc injectors at least. I am doing an ITB h22a4 tune tomorrow with 550's. My si granted E85 running 1600cc which is really about 1200c or so normal fuel. That is at 20-25PSI.

What modifications do you have on the car?

http://www.plxdevices.com/wideband.php It gives you your air to fuel ratio, but more precise and a wider range of voltage readings. The timing is not out just some sharp jumps on the map. tuner should have no issue fixing those. Once the tuner gets to work and turns off closed loop, he should be abl...

you will have to adjust your fuel map a little. Why are you upgrading?

Honestly need a good 3erd gear pull. Your timing map needs smoothed out also. You also really need to get a Wideband O2 Sensor. It does look like you are running a little rich there. It is hard saying much else with such short gear pulls.

Can you post a datalog? just post one on a 3erd gear. Does it still knock in closed loop? also have you tried using the H22a map from hondata to see how it runs?

You really need to get that A/F under control. Fix that you will get some better numbers out of it. Also the parts that spike to 20:1 is dangerous. I know you said you had some issues, but issues like that should have been fixed before going to dyno. good luck! :)

Please do not use that map. If you target 14.7 all the way your going to blow the motor. Also your not even set up for 100% TPS. I am guessing you read the links posted. That will help a lot.

Anyone have a map with H22a4 with ITB 550 injectors or at least an H22 with ITB so I have something I can go off and speed up the process. lol
