LSA E85 Remote Tune Possible?
LSA E85 Remote Tune Possible? Thinking I’ll need a local shop with an engine dyno to do my calibration (tune)…..?
Seeking local or remote “tuner” recommendations for my E85 LSA build. Engine will have 224/232 cam, 10.5-11:1 compression, 1300cc injectors, and 28% increased blower drive. Engine is standalone and will be going into a boat. I do have HP Tuners, dual wideband sensors, run stand, and shorty headers to test fire and run, but no dyno to load until it is in the boat. I do have the stock E67 with original LSA cal in it as a starting point.
Would this be able to be done remote? Get a base established on the run stand for start and idle, then send logs once running under load in the boat?
Thanks for the advice and guidance.

Since I have never seen your boat, and its just a hopefully helpful comment take this with that in mind..
I would go for the engine dyno.. A super flow with a wet load cell would probably be optimum.
Super flow at one time had a Marine setup on some versions that models the power load like a prop.
Once tuned on the dyno, the fine tune on the water should be minor especially if you can find a boat tuner,,
check in to sprint boats the run some wild stuff and would know a guy.. I don't believe any car tuner is going
to nail it unless they already do boats. Its such a different load profile.
I'd probably just install a Stack or a waterproof laptop in the boat. You also should invest in a alcohol test kit.. (See dirt track or aircraft suppliers, or chemical suppliers)
E85 is very erratic at alcohol levels in the general distribution chain.
Find a local chemical supplier and buy a drum of pure ethanol or a Drum of E100 from a fuel distributor to adjust the pump fuel with.
OR
Long shot don't know if they still play in the game or not,, Family that owned Milton Freewater Chevrolet in Oregon was a key developer for the 502 chevy's with GM..
They had a cigarette race boat program and likely know how to tune the engine for a prop application, as well as properly prop the boat for your performance desires..

edit-- No matter if the tuner knows boats or not if they are doing it in person. You tune FI off sensor readings, engine noises, plugs, etc. Does not matter road or water.
The only thing that I know about boat tuning is what I learned from Holley EFI class years ago. Boats are different than cars.
Boats commonly hit places and live in parts of the VE that cars don't.
Boats run at WOT for extended period of times compared to cars WOT blast. i.e., timing, cylinder temp, Lambda

I think it should be easier than a car, a lot less data points (conditions). Yes continual load, like driving a car uphill continuously, but just that. No coasting, no decel, etc….

@FormulaBoat if local is the Chicagoland area I think I know of someone who has LS1 and marine tuning experience.

This is all good info, thanks to everybody. Apology to litter the board with a non-car post, but there is more LS knowledge here than nearly anywhere else combined. I’m in Livonia, MI, about 23 miles from Detroit. Livernois Performance and Lingenfelter are both relatively close, just seeing if I can save $ bu having an experienced E85 LSA tuner do a remote vs taking my fresh build to either of them. I’m also considering to run a carb and MSD ignition box just for the ring break in since a fresh “tune” would likely start out at idle.

This board is LS-centric. Boats, planes, hovercraft, flying saucers..... if it's LS-powered, it goes here!
I have tuned hundreds of boats from stock ls with 2,000+hp blown big blocks and remote tune alot of them. You do not want someone who has only tunes cars to tune it. I wouldnt even bother with the run stand, put it in the boat and then start the tuning process. I would also add a flex fuel sensor if you dont have one already.
