Afm Or Pressure Sensor?

soo a few questions...

here is where i am at...

atm the car has:

-full 3 inch exhaust turbo back split dump

-bosch 040 fuel pump (re-wired)

-adjustable fuel pressure regulator

-fmic using stock piping.

-pod filter

-gfb plumb back and atmo bov

-boost control (bleed valve)

-mv stage 2 shift kit (going in soon)

-drift catch can

-other silly little things like engine damper, turbo timer etc.

-the rest is stock (stock injectors, turbo, internals etc)

now i have a greddy emanage ultimate sitting here and want to put it in and go for a tune in the next few weeks.

my main question is what would be better for me? a z32 afm or the pressure sensor that can be bought for the emu or will the stock afm cope?

i am aimnig for just over 200rwkw maybe 220rwkw (completly street driven) or so as i know the stock injectors max out around 230rwkw (some ppl have got higher but dont want to push them too much)

ive read that with the sensor i will loose tuning points? but the fact is a pressure sensor is about $180 a zf2 is about $300ish..

what way do you guys think i should go? is there anything else i should do before the tune aside from, oil change, plugs etc? would aftermarket fmic piping make much of a difference?

the plan down the track is to get bigger injectors and turbo and retune so keep that in mind.

thanks alot :P

I suggest asking whoever you want to tune the car, as to which method they prefer to tune, MAF or MAP. You wont be able to tell the differnce driving the car, but the tuner will have a prefered method to tune on no doubt.

go MAP if your not going to take long drives that vary in altitude much o/wise go MAF

problem with maps is that the ecu takes a base reading of the manifold pressure at startup to take an atmospheric datum and its tunes are based on that.

If your going on long drives up a few mountains and havent turned your car off since starting it your car will soon start playing silly buggers. Some notice some dont

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      My BMW E39 528i touring

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
