Hondata

Hello forum, I'm in the process of rebuilding my 1997 Honda Prelude Type SH with an H22a4 engine that has a little too many mods that the stock ecu can handle, so I am here with my Hondata S300 installed into her but I can't find a parameter fitting what I've done to my H22, the only ones I see are for supercharged preludes or the stock base tune which obviously wouldn't work as the stock ecu hardly kept the car idling.

I don't have any boost or anything yet but all I've done that could be used better with a tune are Brian Crower Stage 2 NA/High Boost Cams (#BC0032), a Walbro 485lph fuel pump, ID Electronics 1,050cc injectors, AEM Hi-Flow fuel rail and adjustable fuel regulator. I found how to change the injector output so the ecu can recognize that they aren't the regular stock ones but I am having trouble finding out where to put in the information for my cams so the ecu can adjust the timing and fuel mappings accordingly with the new cams, same goes with the fuel pump as well. I'm not asking for someone to make me a base tune (although it would be pretty cool but I'm not expecting anything), I'm just asking for some help with getting my car to run and run well enough to break in and eventually go get her professionally tuned and dialed in once I know she can handle the abuse.

This will need to be tuned on the dyno as fuel and ignition changes will have to be made as well as adjusting the VTEC point.

I figured. Those were my intentions of course but I found a tune with my cams in the vault which I downloaded and then changed up a bit to suit my engine so it should hopefully run fine enough on its own to be broken in and then I'll go take her to a dyno to get properly tuned by someone who knows what they are doing.

I'm sorry but I swore I saw someone provide an answer just yesterday but now it's gone? Well it mentioned something about inputting the ccs for my injectors and adjusting the deadtime for them as well to account for the cams, I already put in the ccs and adjusted the dead time so they'd match the injectors but I couldn't figure out how to tell which numbers were "good numbers" if that makes sense, like I don't know what I'm supposed to be seeing there but I found someone else's tune which claims to have the same engine and cams as my setup so I used that tune as a template and then adjusted everything to suit my specific build such as the injectors and to account for my widebands as well which I remembered seeing the deleted post recommending as well.
