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.
Actually I just realized that we STOPPED there after lots of dialing in, and he's just STARTING and already at more timing, so you're probably right he should start way more conservative and only turn it up from there.
