Tunning Question-Scanmaster

[psycho6cyl]

Ok.trying to increase my tunning understanding. Is lv8-engine load affected by tps? I noticed tps is only 2v but the load is 255. I would think w throttle barely open.load would be less?l. Thx for the clarification

I was thinking it was a function of RPM and MAF readings.

Well im.getting knock @ like 10#s and my afr is only reading 13s. I added 7% fuel thru tt chip. So idk what gives. How can I increase afr?

If you're having any misfiring that will cause the A/F to read lean. Do you have a powerlogger screen grab you can post?


I just went through the same thing with 3 flaky ign modules once. It drove me batshit crazy until I managed to get a good one.

 

[psycho6cyl]

Not able to post only view as of now.. what should I.look.for?

 

[psycho6cyl]

Funny thing about knock once I see it registers and I let off knock.counts go.down w rpm. My exp.has been when ypu lift for.knock it stops..

Depends on how severe the knock is. Once it starts, the rules change. You have to go waaay below the knock threshold before it goes away.


get a good view of it acting up on powerlogger and push the ''print screen'' button. Open up an image viewer and choose ''paste''.

Ok thx will do. Ill try to get a couple.tonight...

her earl hope this shows t.

Assuming you have a PLX and a 3bar, it looks like you went lean as hell while the boost was coming up, then 1/2 second later the knock piled on.

Was your foot all over the place or is the TPS flakey?

 

[psycho6cyl]

Foot was prob half way. I dont think ive gotten over 2v tps bc I have yet to floor it. I dont want to bc of this knock issue..ill take a look.at that run but rpms were increasing yet it went from 10 to 12 on wb

 

[huntsg]
