[Skidoo bachelor]

Does anybody know what primary and secondary spring come in silbers 2018 850 kit, I've texted them about it and get no response. Trying to figure out getting the rpm lower. Nice to get it to run for next season.

Hey dude - its going to be the stock 2017 spring. (150/350) - Let me find the secondary one, I know its one of the firmer ones.

So what’s silbers response to porcelain cracking on plugs, is it from hitting rev limiter..

Or they recommending a top tooth or two gear change..

Detonation, I was running 80% 110 vp race gas 20 clear super unleaded. I sent the ECU back so they could tell me what it was doing. Said had detonation and mis firing going on. I indexed the plugs properly didn't over tighten I think 159 inch pounds if I recall correctly.

Would be easy to gear up with belt drive and I have a one and two tooth larger upper gear on hand. The problem is all the snow is gone in my area so might have to finish getting it dialed next year.

You aint getting enough fuel put on an afr gauge and you will see. Mine did 13.7 AF at wot and its way lean

Aero has ran 13.7 for years, ran well..

13.0 is what I strive for..

I thought most shoot for 12.5 - 12.7 WOT. Can the E-tec run that lean with that much load?

 

[fredw]

12.5 works, little more safer than 13.5 but they both work.. I also have a impulse turbo on the 800 Etec and a/f is ussally glued at 12.8.. Works very well..

If knock sensor is not going off and good fuel is being used, being 13 is not much a problem we found

13.35 is what dynotech reported when they dynoed a bone stock 850.

If you bounce these 850 turbos off rev chip they break plugs and set a det code. Did it to mine multiple times and it's prone to happening with the darn p drive clutch that won't shift and keep the motor loaded.

Mine is a slightly altered boondocker sidekick kit. The thing is a rocket ship now that I have it dialed in the clutch. She needs a slightly improved 5000 to 6000 fuel tune and it's a
Dialed package.

My guess is lots of your issues are clutched in

 

[simbatheking]

how much boost were you running? did you have any other issues causing it to go lean? what did you do to fix it? it wont run that lean for long
