EFR 6758: pls sanity-check my tune
So, my kit is installed. It's finally time to make the transition from N/A to trubo. Before I grenade my fresh engine, would anyone care to perform a sanity-check on my tune?
tech facts:
- EFR 6758, 18 psi
- Megasquirt MS3-Pro
- built VVT engine: eBay forged rods, Supertech pistons (8.6:1), Wiseco rings, oil squirters removed
- 2.5" intercooler pipes, GFB DV+ recirc valve (for now, will use the integral bypass valve when the modifications have passed TÜV scrutineering)
- full 3" SS exhaust system
- 750 cc EV14 injectors, Walbro 190HP fuel pump
- BE stage 2 oil pump
- D585 ignition coils
- 50 mm radiator, coolant reroute, 25 row oil cooler
- european RON 95 fuel with 5% ethanol. I take it equals 'murican 91 octane fuel?
AFR table. Mostly blatantly stolen from MT threads
Ignition table: been running the N/A area with 10:1 compression for 12,000. I suppose it's mostly the boosted cells that need looking at
VVT table: i simply changed the top row from 85 to 250 MPa.

Built engine and street car led me to believe it was okay.
210-230kpa he's running about 1-2* more than I tuned G's car on the 6258 and CA 91 water, being really conservative.
I'd guess his gas is still better than the junk we have here.
So I guess maybe drop 150-210 rows by 1-2*, but otherwise I think it's fine.
