me and my brother are learning how to tune on hondata s300. we were sent a map that was supposed to be tuned for a h22a with i/h/e. it idle perfect but as we got out on the road it was detonating like crazy.

so now we are looking for a base map for high and low cam fuel and ignition so we have something to go with.

so if anyone would have a base map for a jdm h22. i would really appreciate if you could help us out here. thanks

 

You sync your base timing with the distributor?

 

Both are set at 16dbtc... But in the map we were given, there where timing spikes of over 50dbtc.

I'm looking for the stock fuel and ignition curve. Every map I find is either insane one way or the other on both ig and fuel

 

Reference the hondata s300 h22 calibration or the gsr calibration for starting points.
Sync your ignition timing to the s300 system per the instructions provided in the help file.

Then go ahead and proceed to tune the fuel tables until you get them on target.
You would then want to proceed with tuning ignition timing on a dyno or on the street if you know how to properly monitor for knock (plug reading etc).

 

Alright thank you. P72 it is. Car won't even start on the Base prelude map that Hondata has, even with fuel scaled back 15% in low cam, injectors rescaled and some other BS cleaned up, their ignition is off the wall, and I have no basis of stock ignition. The PLX will be here tom. and we are just going to use the P72 map as a starting point. Fuel trims look a bit weak, but won't be a big deal.


We might give timing a little kick but nothing serious, don't have an EGT on the car, so probably only run a few degree's and call it good until we can get some dyno time.

 

for future reference what is an ideal afr to tune to say for idle? partial throttle throughout the rpms? WOT? and after vtec crossover?
