Zmanco Posted April 3, 2007 Share Posted April 3, 2007 I'm getting ready to choose an MS version for my NA L28. A few things about my plans: - I do not plan to go turbo - please don't hold that against me - I already have an MSD 6AL so don't need a rev limiter - I would like to be able to make tuning adjustments via a Palm (even small laptops don't fit in the glove box) From what I can tell from the MS site, I think I want to go with the V3 board as it's the most robust and tolerant of wiring errors. The question is if I go with MS-I or MS-II. MS-I Pros: - has tuning s/w for a Palm - cheaper MS-II Pros: - 12x12 VE table (vs. 8x8 for MS-I) Does this really matter for a NA application? - Autotune support What other significant differences are there? Lastly, does either support control of an electric cooling fan? I can't find it mentioned on the site, but it seems like it would be trivial to add hysteresis for the relay.

proxlamus© Posted April 3, 2007 Share Posted April 3, 2007 Well.. MS1 with Megasquirt n Spark EXTRA has (12x12 fuel/spark maps) http://megasquirt.sourceforge.net/extra/index.html Does it matter?! yes if you want a rock solid AFR all the way across the powerband, the more fine tweaking the better. EXTRA also includes : Features 12x12 fuel tables 12x12 spark tables DualTable code Roger Enns' injector staging code Rev limiter Overboost protection Mappable Air:Fuel Ratio target for use with wideband O2 Coolant temp timing advance Inlet temp timing retard MAPdot accel/decel enrichment Anti-rev / Traction Control feature Over-run fuel cut Afterstart Enrichments Cranking /Priming settings Hybrid Alpha-N Air Density Correction RPM Based Accel Enrichment If you want to check out my car Daniel i can show you the ins and outs, I finally have a laptop for full tuning.

Zmanco Posted April 3, 2007 Author Share Posted April 3, 2007 Thanks Ryan, I didn't realize there were other sources of firmware as well. Wow, lots to get on top of! So MS1 might be the way to go after all. Any thoughts on whether the V3 board is really that much better than the V2.2? It appears to be a more robust design (4 layers, thicker copper), but if the 2.2 is adequate, that's another $50 to spend elsewhere. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted April 3, 2007 Share Posted April 3, 2007 I agree, even ran as fuel only, MS-I with the MegaSquirt n Spark -Extra firmware is the way to go. Just lock your dizzy advance or swap in a turbo dizzy and go for fuel and spark control! I felt the 2.2 board is easier to assemble then the newer board (if you're building it yourself), but the newer board is "fancier" and it is easier to access it's outputs when you start adding stuff with the MSnS-E firmware.

linluv84 Posted April 3, 2007 Share Posted April 3, 2007 If you go with a v3 board with MSnS-e, I have a good fuel only map to get you started... Quote Link to comment Share on other sites More sharing options...
Mack Posted April 3, 2007 Share Posted April 3, 2007 If you got V3 with MS&S_E, I have a .msq for fuel and spark thats seems to be doing the trick (even did about 10K miles of pizza delivery with it) Quote Link to comment Share on other sites More sharing options...
