Preparing .msq for first startup

Preparing .msq for first startup
Ok, the rebuild is progressing very nicely and the engine is probably in the car by today. See https://www.miataturbo.net/forum/sho...332#post309332
The car will be started for the first time early next week. I talked to the guy in the shop doing most of the work on my car and his intention is to start it up with the 550's and MSPNP and not bother with the old ECU.
So, I am preparing a .msq for the 550's. I want to check with you guys if I am taking the proper steps?
1. Install MegaTune 2.25p1 as per CD-ROM
2. Upgrade MegaTune to 2.25p3 from site
3. Choose which firmware 029y4 or HiRes to go with. I don't feel like installing a 0.1uF capacitor right now.
4. Open base map, adjust for 550's*
*) I came up with this using Excel:
I also want to change from F to C. Just replace everything in the .msq and where else?
What else?
Then put it in the car, and:
- Calibrate TPS
- Check sensors for plausible readings (CLT, MAP, ?)
Thanks!

Input on base MSQ wanted!
Thank for the input. I've tried to establish a base map to work with when we get the car started. What I've done is this:
Would like to hear your comments on this map.
- Change to Celsius
- Recalculate MSPNP9495 MSQ from F to C
- Place HiRes code in project folder
- Recalc REQ_FUEL based on 1862cc (83.5mm bore), 550cc, 13.1AFR
- Recalc Cranking PW using Excel
- Change LAMBDA_SENSOR in MegaTune Configurator
- Change EGO settings in MSQ to Wideband
- Re-enter AFR targer table1 because of Volts to AFR change by hand
- Set lower rev limit (6600 soft, 6800 hard)
- Configure boost control basics
- Set overboost protection to 230kPa
- Configure Knock Sensor settings
Would like to hear your comments on this map.

"paul" on the forum (that's his username, search it) has a 94 with a 2560R and 550's. You need his maps. He's posted his timing maps for sure as I've seen them. I think he's posted his fuel ones too. Maybe he will chime in. FWIW, his timing maps are in a thread called "take a look FM, we need your timingz" or something like that.

Thanks, found that and will have that handy.
Couple of questions before we head off:
1. Best configure WBO2 to INNOVATE_0_5_LINEAR and configure its output as such?
2. The MSPNP9495 base map has const baro correction enabled. Is that correct?
3. My injector PW is still 1.2ms. Is that right for RC 550's High Imp?
4. I need a baseline for my accel enrich. How do I scale them?
Thanks!

Thanks, but since I have MS1 (MSPNP9495) Ill have to do TPS or MAP based accel enrich. Not sure which is better. I read TPS gives faster throttle response, but Savvington is having lean tip in at higher RPM?
I will probably just recalc the accel enrich PW just like I recalculcated the cranking PW for the 550's and have the dyno guys figure it out from there.
