I just wanted to post my setup, and say thanks to Braineack and all the others who have been super helpful answering my questions... My car is running AMAZINGLY well now...
My Setup: Greddy manifold Greddy turbo @ 5psi TurboTony Downpipe Custom 2.5" Mandrel Stainless catback to Magnaflow muffler (DP6061 style) RX7 Injectors DiyPNP MegaSquirt w/ GM IAT TurboXS RFL BOV (The wife wanted the loud pshhhh) Flyin Miata Stage 1 Clutch Toyota COPs Yesterday on the dyno... https://www.miataturbo.net/attachmen...ine=1345035619 Why laptop? Because Racecar :) https://www.miataturbo.net/attachmen...ine=1345035619 Engine bay setup (Haven't removed the FMU yet but vac line is disconnected) https://www.miataturbo.net/attachmen...ine=1345035619 And the only dyno graph I really have... https://www.miataturbo.net/attachmen...ine=1345035619 That was with 1.12 correction factor on a Dyno Dynamics... I was unable to go any higher than 6k RPMs because my IAT's were spiking over 200 degrees even with the fans going (The dyno room doesn't get great airflow and it was high humidity yesterday)... Then we did a bit of road tuning, and was able to smooth things out a lot more... AFR's are 11.5ish across the board... And the car is MUCH stronger after the road tuning... Here's my maps... Feel free to critique/advise me... VE Table https://lh5.googleusercontent.com/-z...4/final_ve.png Spark Table (10 degrees base timing on the crank, and I believe 1.5 offset in TS) https://lh3.googleusercontent.com/-a...nal_timing.png AFR Table https://lh4.googleusercontent.com/-o.../final_afr.png I was also able to get rid of 99% of the tip in stumble I had playing with the Accel Enrichment stuff... Does this look okay to you guys? https://www.miataturbo.net/attachmen...ine=1345035619 Thanks again to everybody for all your help... You rock. :party::bowrofl: |
I dont' like your AFR table but you probably know more than me so I'll shut up and cut myself.

What don't you like about it? It may need improvement... I may be overlooking stuff... I've been working long days/nights so lack of sleep may have me missing stuff...

No really, thank you for the advice... I saw earlier in another thread where some people put that 15.4 pad in there... I just get nervous anytime i see my wideband in the 15's... But if Miatas can handle it, i'll definitely do it. MPG FTW! I'll also lean out my overall band a bit too... I'm all about being safe, and I just get nervous when I see low 12's in boost... Its the subaru owner in me lol.. The rocky timing curve was actually created after the dyno when we did the road tune lol... But I will smooth that out... Now that I look at it again you are right its REALLY jagged.. |
I ran my turbo car at 16.7:1 AFR in cruise for years until I finally realized that was not the promised-land I thought it was...then my MPG went up, the head came off, and everything was fine aside from the bent valves from selecting the wrong gear.
The only reason you ever adjust spark angle after you leave the dyno is if you hear detonation. |
We had to play with timing after the dyno because we couldn't do full pulls on the dyno due to the heat soak. I needed better real world scenarios... Next week or the week after i'll be adding an intercooler and throwing it back on the dyno for a real deal final tune.... But I have a 1500 mile road rally I'm taking the car on this weekend so I wanted to make sure I'm good to go for that without major worry...

"I don't know, add some more spark" "What about now" "Oh yeah, I felt at 3hp reduction, that's MBT". You're playing with fire at low RPM, target boost cells. |
Hustler used to be a e-thug that fucked dimes and I looked up to, now he is a pozd up emo ------ who cuts himself.
