502 MPI Tune
Just Wondering If Anyone Had Sent Their ECU Off In The Mail To Be Tuned, And Had A Decent Running Boat Afterwards. I Know I Prop Dyno Would Be The Real Way To Go But Id Probably Have To Drive 10 Plus Hrs To Find A Shop Capable Of Doing So. I Am Not Looking To Squeeze Every Last Bit Of Power Out of My Setup , I Just Dont Want It To Run Lean And Damage Anything.Boat Already Had A Procharger And I Dont Think PO Did Any Kind Of Tuning I Added A 168731 Cam ( 500Efi Cam ) And Cmi Exhaust Might Have To Go .030 Over After I Measure Bores

really need to tune it on the water,,prochargers and vortech's are kinda of a pita to tune.you should get o2 bungs put into your pipes.
|
Why would just not have it tuned on a dyno???
and why does every word start with a capitol letter in all of your posts?? |

+1 on the dyno |
I Suppose , I Am Doing All Of My Own Work Guess I Was Just Trying To Do As Much Myself As I Could.
Would Tuning On An Engine Dyno And Actual In Boat On Water Be The Same As Far As Load And Mapping ? Its A Habit I Cant Really Break, It Comes From Years Service Writing Work Orders, For Some Reason The Company At The Time Thought It Looked More Professional.... |
Come on now, service writers use ALL CAPS! Lol!
|
FWIW, a friend sent his ECU to Alexi at Boostpower and had it programmed. According to him boat runs top notch. Call him and discuss it and see what his thoughts are maybe.

I think with all the money I'm investing in my engine I will just have to suck it up and take it to someone that can tune it on the water for best results. There is not much for performance Marine where I'm located
Can bungs be added to the jacketed section of exhaust to where they will stay dry? I will try searching more on that subject Btw that was extremely difficult not doing the caps typing, took about 3 times as long lol |
Yes, you can have an O2 bung welded into CMI's.
Engine dyno will get you very close, especially if they run your headers and engine accessories. |
