My new MAF setup + extra pictures

[CasopoliS]

If you ever decide to sell, shoot me a pm.

Will do Mr. Hot Sig. I might try to cap the BPV to see how it runs. Like I said... it runs great now, which it hasn't in a while. So I hate to change anything. I still think keeping some of the air in the system is good. Not for stalling issues, just for performance. Mabye I am wrong.

My local tuner will look into a blow-by MAF replacement. They are also looking into the SAFC II. I told them nobody can get it to work and explained the issues. They told me they can't imagine not being able to get around the problems. They have never not been able to install one when asked. They tune on them all the time. They took an old school Porsche and put on standalone and converted it to electronic fuel injection. I forget the HP but I remember it was rediculous. I just thought it was a cool project.

with money anything is possible, the thing is a afc is a good mod cause it doesnt cost alot compared to other ems systems, make sure you know what it will cost you or it might not be worth it compared to getting something like an mpi or haltec

Yea it was between DSM's AFC and the MPI. I am not really an experienced tuner, though I hear the MPI is not bad assuming its installed right. Something like THIS could happen.... poor joka1

 

[jeffmsp]

i think both dsms or the mpi would be fine. maybe just the afc if you dont wanna build the motor right away, and im sure it will have an ok resale value if u decide to go mpi later + aftermarket rods etc.

Also, if you mount your IAT sensor on the cold side and your MAF on the hot side, the readings won't correspond. I'm not sure if that's a big deal to the ECU, but it would be nice to see some AFR's.

I had wondered about this issue myself. However, I thought that it might actually work to our advantage, as there would be a larger discrepancy between the temp read by the IAT and the temp measured by the MAF thereby allowing the engine to blow more air through the MAF before fuel cut was initiated.

I had started a thread a while ago about using a GM blow-through MAF that DSMs switch to sometimes. It requires a converter for the ECU to read the sensor, but that setup is made for what you are doing, not to mention would give you more headroom for power. Unfortunately, I haven't seen a converter that works for our ECU yet. That's something that I would like to see... hint hint vendors.

I looked this up before, but Granatelli, who make alot of these don't seem to offer anything for imports. I have read on a Miata forum (Flying Miata?) that you can use an RX7 MAF which is apparently bigger, but I haven't heard of anyone on this forum doing this. If I upgrade the MAF, I might go along the lines of Bigg Tim.

the rx7 is a vaf, not a maf i think. either way i dont think 1.8bp people have been running them on the charge side, needs to go before the turbo i think.

escortracing.com and miata.net for more info.

I have considered doing this myself before.. but the wires seem to be so tight in that region.. how did you make them stretch?

Unwraped the elec. tape around the IAT and MAF wire combo. In there are the two sets of wires, which are individually wrapped to some extent. I spilt them apart carefully with an exacto knife, then re-wrapped each set in electrical tape so it looked good. Both reach just fine, and the IAT will reach its new home as well. (when I get it done)

no splicing of wires involved?

good boy, looks good bro.

I would like to get something off my chest... some kid with a Cavalier + stickers and euro tails flew off the line while I was next to him. Then his buddies in some sticker'ed-up civics zoomed by me then back in front of me like they were in F&F or something. I hate idiots that street race in the dumbest areas (small-town area with cops everywhere and traffic everwhere). Then the kid will probably go tell people he burned me. I hope no one on here is like that. F'ing kids.

I pulled up behind the last civic at the next stop light and reved it to let off the hiss. When he looked back I just shook my head back and forth (no) . He nodded his head in understanding that I could kill them if I even tried, and even more-so if I click the 'setting B' button. Ok I feel better now.... I know.... I'm a h8ter.

Guess I just jacked my own thread.

 

[CasopoliS]

none. other than re-installing the FCD. the wires are now built into the 'loom' and are un-noticable. Too bad I will have to get rid of my fcd anyway when I install my Airflow Logistics AFC. Yes I will be selling it.

hmmm I think it's time to go to my shop tonight

From what I can gather.. our car will function properly if set up this way with a blow off valve since there won't be any lost air.. is that a correct assumption?

It will not stall because you are venting un-metered air. Your MAF will only see what your engine sees. Good luck with the pipe-choppin!

Hmm now I wonder, the only difference between yours and mine will be that I will not have a BPV as well as a BOV. I will be running a single BOV. Think I should cap off the inlet on the intake pipe or just throw a small filter on it?

Cap it. There really is no need for the BPV, so you will be ok.

I will say that after I shift I have instant power and I think it is due to some of the air recirculating. I can burn through 1st, 2nd, and 3rd while shifting.... no lag between shifts. (wrc)

Guess I'll have to test out the alternate method and see how that functions.. I wonder if there is a stronger version of the MAF we can acquire somehwere to make sure it can handle this kind of pressure. However.. thinking about it.. the only difference is instead of being sucked it will be pushed... prolly by about the same pressure level... hmmm I guess we'll see!



Edit:

Judging from your mod list the only difference between myself and you will be the lightened flywheel that I have and unichip... any dyno numbers Casapolis? before vs after?

No. I will get to the dyno after I install my AFC. What do you like most about your flywheel, and which one is it? Thanks.

I hate you so much.
Screw you and the rims you rode in on.
