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?
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:
