Having this week off I've had a lot of time to get the hang of the adjustments in megasquirt, as well as tap the return into the pan and put some flow force injectors on

I know they're 640cc

 

 

This car is so much fun, turbo setup is great, everything as promised.. would definitely recommend mkturbo to a friend

 

Yes the OBD-2 cars run lean as hell compared to the rich early cars. Mine was 15:1 on the dyno with a header and intake with the stock ECU

 

Fuel efficiency. I run 15-16:1 at low load kpa. Not a big deal.

 

I am glad to hear you are enjoying it.

 

He was worried cause it was fairly lean at WOT. I run mine similar to yours. It is 15.8-16 anywhere up to 75kpa or so.

*squirrels this info away* Good to know. My 1.6 ran pig rich anywhere but cruise.

 

Car is making approx 200 kpa at peak boost (13.5 psi) and I feel like I'm pushing my luck with the stock longblock.
I understand there are many things that come into affect when it comes to this topic but I'd like to lower boost to around 10 to not have to worry about it. I did remove wastegate arm and make sure didn't have added tension before putting it on but I'll check again when the rain stops.


I'll toss my spark map here as well just for ***** and gigs. I took a map Brain posted in an older thread and pulled 2 or 3 deg everywhere in boost for now. Quite sure its super conservative. I don't have a knock sensor as of right now*

 

Just got some help from a nice guy on the local miata facebook page, definitely boost creep... will be taking off the turbo tomorrow and porting it to the best of my abilities

 

Also this is what she's looking like currently, with my friends hardtop

 

hopefully today can make it down to the shop and port this waste gate flapper.. My tools at home are limited to a metal file for this

 

I would absolutely not want to try porting the turbo with a metal file. Hell I hate doing it with my dremel and not my bigger die grinder.

 

Lars recommended the $50 Harbor Freight electric die grinder and you can't go wrong with that, I was able to get the job done with a set of cheap grinding bits too, knocked out the porting in 10 minutes, super easy.

 

Yep that is personally the die grinder I use along with a set of $30 carbide bits from Amazon. Really I only use 1 bit out of the set of 6/7 that I bought years ago.

 

But, but, that's almost 1/3 the price of a new turbo!

 

Not the cleanest thing in the world.. But it was done with a drill bit. This will hopefully bring me closer to waste gate pressure. The actual hole for th waste gate flapper was already opened up by PO

 

If that ends up not being enough ans If you have time this weekend, you can swing by with it. I have a dremel and bits.

 

sweeet, I'll find out later tonight
