Take a look at my maps before boost?
 
1 Attachment(s)
Hello friends. Turbo is going on in the next week or two. I re-binned my spark and fuel tables and wanted someone to double check my tune before I go out for my first sessions with boost. I think my ignition tables look pretty conservative, but want a second opinion. Planning on 91 octane for now....

My Setup:
  • 97 1.8l with MS3PNP
  • FF640's
  • BW EFR6258, running low boost spring in a Turbosmart actuator (7-8 psi). Planning wastegate only until I can get on the dyno (stock internals, keeping boost low for now, will build next spring maybe? wish me luck)
  • Kraken low mount
  • Fab9 S1 intercooler
Also, any advice for first drive would be appreciated. Plan on auto-tune on easy to get fueling dialed in quickly. Any other suggestions?

.msq is attached!

Bump!

I attached ignition table for those who don't want to open the tune. I'm not super confident in it so looking for some feedback before I get in the car and start preliminary tuning under boost.

Also, for fun, I attempted to gather some data to set my Knock tables up before going turbo a couple of weeks ago. I did a couple of baseline runs with the attached ignition tables, and a couple more runs with the whole table dialed back an additional 5 degrees to see if there was a difference. I have already scaled individual cylinder gains prior to this analysis, they are grouped about as close as I think I can get with the pre-defined gain selections.

For reference, I ended up starting with all of the cylinders gains maxed at 2.000 and then backed the other cylinders off based on some excel data. I don't think I'll turn on knock control for the initial tuning under boost as I haven't had time to trial these settings on some more extensive runs. I'm sure how they will behave in transient situations, as I only did a handful of pulls at WOT and haven't analyzed against a scatter plot of a more comprehensive operating range. Settings below:
