12-13psi goal.


What do I need to add to enable this to work past 11psi? Just the GM 3bar map sensor? Is there a website or something I can check out? Linky links?

thanks fellas.

 

would joo prease help me? I'll owe you a burrito

 

jo0 need a 3bar map sensor, but runnin that much boost on the stock sized fuel maps isnt a very good idea

 

Yeah, but its an accord. F22b2 blocks are $100 and no one wants em. It would be cool to experiment.

 

stock sized fuel maps, not stock shortblock

 

stock fuel maps = lean = heat = preignition = "holy **** a piston just shot through my hood!"

 

nonono, stock SIZE fuel maps.... the stock size is only meant for 0 thru 1 bar (atmospheric). With the afc hack, you're makign the maps very coarse, with a 3bar sensor, you're making it cover 3bar instead of 1bar... and to top it off, ,you're using the extreme vacuum section cuz u'll be getting the equivilent of about 70% map cut!

 

The stock fuel maps, once altered, would be fine since the Honda ECU interpolates values. To avoid loss of resolution on your MAP input, could I suggest a GM 2 bar MAP which is good to 14.5 psi?

Also, your ignition advance, which is bad enough with the AFC hack and stock MAP, is going to be worse. You really need to be able to alter your stock fuel maps (at which point you can alter your ignition maps for proper retard). Try PMing GimpyAccord or reading up on PGMFI about swapping a P06/P28 into your Accord.

 

2bar = 29 psi

**** it 10psi it is

 

The 1st bar is vacuum.. so a 2bar sensor can only read 1 bar of boost....

And joseph, i already talked to him about covnerting, he doesnt really want to. he wants the world of ecu hackign to bend to his whim to hold onto his accord ecu

 

Sad, the engine isn't going to last long IMEO. There's no way to properly control ignition timing with an AFC hack save via altering ignition tables. BTMs just don't cut it, especially if you stretch the ignition map further with a GM 2bar.

I believe GimpyAccord/Andrew Shinn mentioned PT3 maps being of the incomprehensible variety I found in the USDM PE7, PK2, PK3, and several others... PM him and he'll give you several reasons that I am unaware of why he switched to P28 - he's not a stupid guy and would know.

You might also consider a stand alone at this point. None of the stuff involved is that hard or expensive (I live in the land of $35 P28), but it's a lot to swallow all at once to learn everything involved, and somewhat expensive if you farm some of it out to others.

 

How about getting 500 or 550cc injectors which should allow you do boost a little more?
