I'm new to the tuning scene and man it shows.
I'm running a 400 small block with stock internals (rebuilt) procomp heads 190 with 64 cc gasket match ported to felpro 1207 intake gaskets, comp cam 280xfi .552in .547ex 113 lobe seperation with 1.6 roller rockers and matched springs and push rods. Fully ported super ram with bbk 52mm throttle body and tpis afpr set at 45psi, and 30lb injectors. Trans is a 700r4 2800 stall b&m torque converter klone steels alto reds kevlar bands transgo valve body and shift kit. Out back is a 3.27 9 bolt posi for now.

Everything is run by accel gen 6. having problems with fuel curves its running rich .

I was wondering if anyone has a setup close to or like this that could help me out or even a place to purchase a program to run this setup

thanks for any help or comments

you might try lowering fuel pressure to 38 lbs.

 

wait what pcm are you using?

 

using accel gen 6 with calmap 6.32 ecm #015013

 

That's old but good stuff for it's time. As mentionmed try lowering fuel pressure first to see what happens.

If you need something further let me know, I'm an Accel EMIC.

 

dropped the fuel pressure down to 40psi with the vacuume hose off car runs alot better ( thanks old z mzn ) but i can't seen to get it to idle under 1500 and now its lean going to reset the timing tps replace the plugs and see what happens
Thanks

set the timing at 16 deg inital,tps at 0.54, volts dropped fuel press to 38 psi. its running rich black smoke out the back idle is now at around 1000 rpm
any ideas
ready to go carb

 

Set base timming to factory spec of 6 degs, tune timing.
I know some disagree but I like higher fuel PSI. You will get a better more complete burn from higher fuel psi due to smaller droplets. I run 47-51 in all my cars. Again you will need to tune it for best results.
Either find a friend or very good shop to teach ya or do it.
Dont give in to carbs!!!

 

is this a maf or sd setup? sfi or batch fire?
when you change your timing you must let the computer know the correct timing.

I know it is fun to start pulling levers and magically hope for power to appear, but this will tell you how to do it on purpose.

 

its a speed density system 1 bar map with the batch fire
