ok so i been setting up a base map to take my car to dyno

specs

tuning with crome

b18a1
p75 chipped
450cc black top dual spray injectors
stock everything
t3t4 turbo 68 trim
aem wide band 02 its running at 13.9 14.1 want it at 11.6 - 12.8 cant figure it out

i am getting a knock till 2100 rpms



ignition retard at .75 degree
turbocharger efficiency 180%
battery offet is for 450cc dsm an it reads out

batt [16.0 ] [14.0] [13.0] [12.0] [11.0] [9.0] [7.0]
inj [ 0.19 ] [0.45] [0.55] [0.67] [0.81] [1.22] [1.72]

need help plz any info would be great
any ideas on what needs to be fixed

 

a general rule of thumb for a basemap is to retard .5 degrees of timing per pound of boost, compounded. im not sure if there is a setting in crome but you should switch to straight table timing in boost (makes it easier to tune).

right now, your car would be fine to drive to the dyno assuming you stay out of boost and you really dont have a knock "until 2100rpm."

 

it's not likely you have knock that low on a stock A1, unless it's rod knock. try retarding your distributor until you can have someone tune it.

 

i figured out why it was doing the stupid knock my friend put in 5w30 when i told him not to thank god i didnt drive the car it came out like water put in the new oil an its running smooth

alright ill set my base map to .5 per pound see how it goes

 

ok so now i set my boost retard at .5% an now im getting major fuel cut at 9 psi

 

I'm curious as to why you're pushing the car to 9psi if you should only be basemapping to get to the dyno?

 

my external wastegate is 9psi

 

after doing more reading up on basic tuning got the car to run with no fuel cut now at all. so next week it will be at the dyno

 

That doesnt mean you have to drive at 9psi...
Set the boost cut to 2psi and keep your right foot out of boost until you get it tuned.

 

Co-sign!!!

 

that is the dumbest **** i've ever heard.

 

then plz tell us sence its so "dumb " . why isnt my motor have a knock sound anymore after adding a thinker oil an after the tune its running strong plz tell us . why my old oil my buddy put in was the same as water coming out of a hose please tell us. don't worry ill wait

 

because if a stock motor is getting a bottom end knock on the oil recommended for it.. the problem isn't the oil.

 

You can put in a higher viscosity oil like you obviously did and it will only mask the sounds/symptoms. This is an old trick used by shady car salesman. If your engine is knocking you're already screwed. I'm boosted and I run what Honda recommends. 5W30 and it doesn't flow out of the engine like water when I do oil changes either. Now more than likely your buddy put something in with the oil like Seafoam because that **** will have your oil at the consistency of ink.

 

doe doe

 

Best to just **** in the engine!

 

op send me a copy of your map siregcivic@gmail.com

what is your afr at 9psi ?

 

and if your just tuning or flashing chips per say and do not have a wideband installled... expect your engine to go boom.....

also for basemap i pull .75-.9 per psi of boost until on the dyno i will fine tune ignition map after the fuel map is dialed in

 

0.9* per PSI on a stock B18A1 is absurd. On stock ignition you don't even need to start retarding until 3 PSI. You're just wasting dyno time if you take out more than 0.5*
But since the OP is driving like an idiot on a basemap what's the point in making boost adjustments at all...
