Intake + MBC = 14.3 @ 98mph

[InsidiousMSP]

Went to the track last night. My first run of the night with only a few minutes to cool down after a 45 minute drive:

My mods:
- Short-Ram Intake
- Joe P. MBC @ 10-12psi
- Joe P. FPR
- Joe P. FCD

Stock tires. Stock exhaust. Pump gas. No flash.

My first run turned out to be the best that night. Made a couple of 14.4 @ 97-98mph runs. And a couple of bad ones where 2nd gear didn't like me. Launching this car is a pain. Launch too hard and it gets insane wheel hop (needs better motor mounts). Launch too soft and it bogs first gear until ~4200rpm then starts to spin -- side effect of the FCD where the MAF signal changes.

Can't wait to head back to the track when I get my 3" downpipe & exhaust on.

i was gonna say- people have been problems running double digit boost after the flash. i'd keep the ECU the old way and just get colder plugs. sounds like to avoid the hesitation, mazda increased timing= not good with high boost levels...

 

[changedman]

very nice times, by the way

 

[STLBLKMSP]

way to go, it will be insteresting to see what you do with the other mods that you are going to be putting on.

Exactly why I'm not getting the flash.

Nice times! Keep us posted on what you do with an exhaust.

Yeah, next time at the track I will have a full 3" downpipe & exhaust (no cats), running ~16psi with 116 octane. Hope to find stiffer motor mounts too.

InsidiousMSP - nice job dude. You always hear in the mags how launching is hard....

Question - I'd like your opinion on something. What do you think of 9psi with the flash, 94 octaine (sp?), cold plugs? Sounds like the engine should be ok.....right?

Though I'm not sure how much more advanced the timing is with the flash, 9psi is the most I'd run with it, as advised by Chojin.

Has anyone mention what the new timing was set to? Just curious.

first off all :

- We have a knock sensor !

- Running with a proper gaz (94 minimum), proper colder plug is very safe to run with 9 or 10psi of boost. Don't forget, the compagnies add a LOT "goods" for safety on new car.

 

[REMillers]

True, but the knock sensor doesn't really help in those situations. It is just going to retard the timing for a bit. But it will no stop the knock in a long term situation, and eventually you will run into problems if not properly addressed.
Doubt the timing is advanced that much more, still curious on just how many degrees it went.

curious myself what would be best....my plan is to run ~ 12-14psi with FMIC, CAI, cat-back exhaust & Joe P equipment....is it better to not get flashed? Obviously I haven't had it done, and I'm wondering which would be better.
