I agree DS and I should have been more clear with my post.  I just want a "base" tune to be half way close when I do go to a tuner.  I don't have an O2 sensor and the exhaust is only 10" long.  I just didn't want to start with a blank slate. 

And Outfront won't update my ECU for 15lbs boost, said there are too many variables.  He said I should get it on a dyno.  I do understand that there are a lot of variables in play(intercooler, compression, cam, turbo, etc). 

Mike is set up for 15lbs with a tune from them, I wonder how hard it would be to copy his and update mine?  DS?  Enemy?  it is an EMS brand ECU, Stinger model.  He said that the tunes were not locked.

So truth be told, I am not a John of outfront fan.  Not saying he doesn't know what he's doing just don't agree with the way he does many things.

Now, I know big Dave bought his  turnkey engine from John, I thought Mike did too but I'm sure you can correct me on mikes engine. So based on friends personal experience and many many comments on forums and fb rail groups....... John isnt interested in really helping if you aren't spending good money. Now, my guess is that a lot of this is due to either he has paid to have tunes written for his engine builds or he himself has produced the tunes. Either way, whoever did, there are no provisions surrounding anything other then his build type. I always disagreed with the fact that Glenn old green rail didnt run an o2 sensor. Didnt see one on big daves or mikes either. Jerry's is a diff story altogether. I am no expert so I could be waaaaay off.  If there is no o2 sensor then the ecu cannot run in closed loop. As a matter of fact, he removed all sensors and actuators that were not needed as an essential system, his idea of essential. I full understand why, he's selling 5 wire turnkey engines. I believe in all the additional sensors. even though I'm not shooting for max hp, Those additional sensors activate additional safety systems that I want. 

I looked at bigdaves laptop and tuning software once. I was surprised at the tune and explained why he was having some idle issues that an adjustment of the tps improved but didn't cure. He didn't have access to the key portions of the ecu in that tuning software. Not saying  all of John's ecu's are set that way as I have no idea but John told him it was unlocked.

As far as copying mikes tune, to be installed into your ecu....... yes and no. Yes you can do it if the ecu is indeed unlocked/open source. If your both running very similar cams or same cam and the same compression ratio then yes . If your running a lower comp ratio then mike then still yes as his timing map has had timing pulled for the higher comp ratio.  Next piece of the puzzle is what else the ecu looks at but if yours is the 5 wire then all can be adjusted or should be able to adjust if 8ts a good system.. Big hurdle will be lack of an 02 sensor to tune yourself. I doubt there's an auto tune function in that ecu but even with out, as long as you can data log the run, you can live tune it. Again, you need a reliable 02 sensor for that to be possible. If your tail pipe is short then the 02 sensor reading will be worthless below a certain rpm because wind will blow up in the tail pipe and screw the reading. No big deal, tune the lower cells in your garage at home. 

So " a lot of variables "  could have many meanings. Referring to mikes engine for this, if you 2 have the same size inj's, same stroke and bore, same comp ratio or his is slightly higher, as in half to a full point higher,,if your running the same crank/cam sensors, same throttle bodies and tps.......I see no reason not to and then live tune for the fine tune. You'll need some sort of 02 sensor reading for that. If your running leaded fuel that will shorten the 02 sensors life.

I would like a tech3 mid engine V8 some day. 

Almost ready to install my engine, it has been a lot of issues, but getting there

Ran across this video yesterday. Irregardless I still like the tech 3.  I'm starting to lean towards a v8 myself. Either the smaller one with a sc or the 6.2 warmed up left n/a.

Desert Dynamics.Nice car for sure.
