Hey all. 1994 Miata, stock other than ghetto intake with AIT to eliminate MAF.
Brain built MS3, I have done a bit to VE Analyze. The car is not a daily driver, just a fun car. Wondering if I can get some opinions on my AFR and spark tables. I feel like it is a bit lean at points. |
Post a datalog, then we can tell you if it's lean or not.
|
Will do! Just want to make sure I am thinking about this correctly though. The auto tune will try to get to whatever I set for a value, right? 16 in the cruise range seems a bit high to me.
|
16 is fine for cruising. Your 100 kpa is too lean though, that should be more in the 13.5ish range.
|
Thanks! I can't get to 100 KPA because of my altitude, but it should be tuned anyway!

Here are a couple of logs if anyone wants to have a look. The first one is a lunatic WOT uphill run, 1st through 4th gear. Second is a normal run around the neighborhood.
Also, and sorry to be a n00b on this, but I don't believe I have a good way to review the logs - what do you all prefer for a view in the viewer? I just feel like total data overload... |
Not too terrible, but a few questions:
- If you want to make more power, run richer AFRs at full MAP (seems to be around 85-ish in your case). 13 to 13.5 would probably be a good start. - Your MAP seems pretty erratic. Where do you have the sensor attached? - You have EGO enabled under full throttle. That's pretty unusual. Any particular reason? |
- thanks on the AFR- I am at 5200 feet (but that will vary from sea level to 9000 feet).
- probably it is not in an ideal spot. Currently on the front of the IM (there was an unused port). I seem to remember reading the rear of the manifold was a better spot. - honestly- I already began googling EGO. I left it setup as it came with Brain's baseman. I don't know enough to know (yet!). Thanks for the help. I am discussing Sav's used BEGI 2554 setup, so I need to get dialed in before adding boost! |
13.5 @ 100kpa? I didn't even look at this dudes table and I think that's a little bit on the lean side. Let me finish these couple of beers that are sitting in front of me and I will get back to you.
