Help needed 16-17 AFR's m50tub28

Pretty impresive! Get your own tune and youll jump some more ponies and correct the afr!

so here is an update from my build.

sold the coupe, bought a 88 sedan and throwed the m50franken there..

and this happened:



pretty good for a 2.8 right?? constant 5 passes with same numbers all of them done in 3rd g260+3.73lsd

the only difference is that i added miller war and the tune was done by my self.

please give me your opinions of the results. i am learnig to use the war and so...

oh, forgot to compare..

the car made 21whp and 11wtq more than the last run. absolutely no change in the engine, just added the miller.

225whp sounds pretty good for a 2.8!

So i recently build a m50tub28 using the following combo:

m52 crank
m52 rods
m50tu pistons
m50tu block
m50NV head with s50 cams
stock 17# injectors
stock maf
using 413 ecu from a 1993 325i

which should end as a 2.8l with 11.0:1 CR, the block was completly refreshed;

fresh hone, new rings, rod & main bearings, guides and tensioner, new stock thickness HG, etc..

the head has new valve seals and the valves themselves were reground and they are sitting as they should.

the engine has about 400-500 miles into the brake-in, did a compression test yesterday (warm engine) and the results are:

1 - 180
2 - 175
3 - 180
4 - 180
5 - 185
6 - 180

today i was doing a baseline dyno and here is what is messing with my mind


180whp
152wtq
and 16-17 afr's

the run was done in 3rd and we did only one because of the bad afr's

please feel free to comment and possibly help me identifing the problem, i know that i am using the wrong map for the engine as i have more CR than stock and more displacement than the 2.5l but 17 is too damn high?

what do you guys recommend?

thank you in advance!

Are the compression those compression numbers ok for a 11:1 CR? what are (more or less) the numbers I should expect from a stock 2.8?
