Checking out my Hondata Maps. and it seems like its running quite a bit of timing for a N/A motor. this is the US p30 Bin. is it just me that thinks this is quite a bit of timing or am i wrong?

Can't read your tables, but some N/A motors like as much as 30 degrees total timing. My street car likes about 26.

 

Also, different motor setups like different amounts of timing etc.
You need to provide more details about your setup along with bigger screen shots.

 

is that better.. BTW this is a BASEMAP calibration on Hondata S300..

 

Looks o.k. to me. That's a stock 92-95 Del Sol SI map. When tuning-after a/f,VTEC, and cam gears are done-I try to add a degree in columns 9 & 10 to see if the motor likes it. If not I will try taking out a degree. I try to arrive at the minimum amount of timing that makes the most power. In other words, if the motor makes the same power with 27 & 28 degrees of total timing, I will go with 27.

 

Looks like a stock map with 2 deg added all over.

 

Looks normal and not alot.

 

i dunno im getting weird half throttle gitters and the AFR is smoothe.

A crappy oxygen sensor has those symptoms

 

its a brand new O2 sensor and im running a PLX M300 AFR is 13.9-14.2 cruising

 

Try disabling o2 feedback.
Also, make sure your timing is synced to your dizzy.
Set your lowcam map to 16.5 deg, then shoot your ignition timing to 16.5 deg

Yep and make sure the car is below 800 rpm when doing this.

 

post the graph of ign map as well ... you can tell alot more from there. why you jump form 26 to 28 then back to 26 on full load column ?

 

LOL i have no clue why the ignition goes up and then drops in higher RPM's

 

what motor r u runing? if u r running a B16 motor then u can drop the timing down by like 1.5-2*. stock B16 maps have overall timing around 26*. if u have a B18C motor, LS/V, B20/Vtec then that map is good for a starting point. smaller displacement B series motor has less timing than bigger displacement.

start off with around 25-26* total timing and then bump it up on a dyno.

like stated b4, set the idle time to 16.5* not the 18.5 u have. then sync the dizzy to the ecu timing
