Finally got so time to play with the haltech today since i got it 2 months ago . Ive got a pnp s5 base map on and I'm slowly getting it all set up to run. I got the timing zeroed out perfectly and got the idle smooth. I took it out for a drive and it runs pretty decent except lol no boost . Its feeling like fuel cut but i just don't understand where the problem is. need a guru to look over my map here and see if we can spot the problem. I can get a log posted tomorrow.

what size injectors??

8ms of fuel at 1psi is a lot of fuel and will put your primary injectors at 100% duty cycle at higher RPM,

i would have thought more like 5.5ms with stock injectors and 4ms with some 1000's

 

Yeah... you need to lean it out. WAY too much fuel.

 

720's 750's

 

Heres some logs i recorded today. I made some adjustments to the fuel maps.


I recorded 3 logs of this issue and the one labeled stumble3 is the best i got. Near the end of the log you will see the issue. I don't think its any kind of boost leak because the kpa stays consistent. In the fuel base you will see it. Its spiking from 3ms to 7ms when the manifold pressure begins to rise.

That map needs a lot of work.

 

you need to go back to basics,

remove all the load points, go back to a basic 500rpm load point etc, you dont need all those points in there and your just making your life hard..

whats your email, ill fix it up a little and send it to you

Do yourself a favor and purchase a good wideband.

 

i have an lc1 on AVI1.

 

Ok i made some changes based on what what you said 10sec. It was way the hell off.

I have an lc1 wb already on an input so i made the adjustments across the board to lower the inj duty down to where its supposed to be. It does not have the boost problem anymore lol, but still have a few questions about how conservative this timing map is. Im planning on running just around 12-13 psi but i dont wanna chance anything bad happening. Whats the rule of thumb for safe timing at higher psi levels?

Updated Map.

Looks better!
What are your AFR's @ like 10 PSI and 6500K?

 

I have yet to push it that far yet for fear of knock. Im currently going over new logs to see if i need to fix any lean areas. Would 10s-11s be too rich for 10psi?

 

emailing you something to work from,

that second map is very very wrong and wont be good...

just check your email go from there

 

Ok ill give it a run tomorrow and see how it does.

 

just keep a eye on the mixtrures, i havent done any street cars with injectors that small, the timing map will be in the ball park and gives you something so you wont blow the motor to bits

 

wow right on the money! well, i do need to clean up a few lean spots but lookin way way better

posting logs tonight


thanks 10sec

 

sweet, glad it worked out

 

now go get it tuned.
