I want to get opinions about this map ( timing in vtec). Good or bad. i'm running 94 octanes pump gas available in quebec, canada. This is my setup

Engine management: hondata s-300

engine:
b20
block gard
eagle rods
acl race bearings
cp pistons 9:1
cometic head gasket
golden eagle studs

head:
gsr head
gsr cams
omni power valvetrain with titanium retainers
port and polish
skunk2 intake
70mm omni power throttle body match port

turbo:
gt3582r at 18 psi
precision intercooler
1000cc precision injectors

392 whp and 298 torque on mustang dyno
vtec at 4700rpm
cut off at 8000 rpm

here's the link of the map

waiting for comments thanks

 

1.) Thats a crap-ton of ignition. I dont even run that much on E85.
2.) Whats with the -10* valley in column 7?
3.) Take it to a tuner.

 

Stock map sensor and 18psi and 10+ deg too much ignition with pump gas no no no. And i think this belongs to EMS area. I would start like 0psi 32deg then retard it like -,75deg/psi so it would have about 22-24deg at 11psi and way less at 18psi with correct map sensor. I wonder why you havent crack sleeve yet due detonation. Or then your distributor is not in sync.

 

Scary!!! CTRL-D lol

 

 

Lol

 

^^ lol detonation's mascot? haha

 

Thanks that's what i wanted to know. i'm running a 3bar map sensor by the way. It as been tuned on dyno but i blown 2 engines. You guys confirmed what i tought, to much timming!!

 

Map you shared shows last boost column 11.4psi and thats limit of stock map, do you have right map sensor selected from properties/options?

 

The tuner entered a custom map sensor with is value but seem ain't right lol!!! It's a 3bar omni power map sensor and the car boost at 18 psi for sure...

here's a link of a pic to see my setup

Your pistons are gettIng toast

 

i wouldnt drive that thing with the map looking the way it does. as stated it only goes up to 11.4 psi in the map, and at that you have probably 10 degrees too much timing from 5000 rpm and up. the rest of your setup is good but please get a new tuner.

here is a screenshot of a conservative basic street tune done on a motor similar to yours but with a slightly smaller turbo and only 12 psi


it will help you get the idea.

 

thanks for the comments
