Title: 413 s52 tune without a modified maf?
Post by: thomasetti.racing on January 27, 2014, 07:36:34 PM

i can't seem to find any tunes that are for a s52 with obd1 manifold without a upgraded mass air flow sensor. are there any out there? i see that there are some for a s50 but no s52. hopefully i'm not missing something obvious. thanks!

same case here, i got an M50 with M52 2.8 rotating assembly which basically makes it obd1 m52, but i can't find a tune for the same setup of injectors... etc. would love to have more tunes in the data base for such combinations !

Hi Guys,

Truth be told, you can easily get away with the s50 performance tune pretty easily as a starting point. What size injectors do you guys have? I will see if I have anything else I can post, but let me know what size injectors you have.

Most people slap the 3.5" MAF on the S52 while they are going through the trouble of swapping it into an OBDI car.

hey there :)

is it alright to do load the S50 tune into my 2.8 stroked M50 engine?
i got a little bit of a higher compression due to using 2.5 M50tu pistons instead of the 2.8 pistons, i believe that makes the compression around 11.25 instead of the stock 10.50

the injectors i'm using are the green stock injectors, 17# i believe.

right now i'm confused on what to use, M50 performance tune, S50 performance tune, or what.

thanks for your time and effort guys :)
