EH. Since i got no help from H-T... here. LSV computer question.

X2 everybody swears that if you run it with out tuning it will blow or not run right.But if your not dogging the car I dont see why it would hurt anything.My friend had three motors never tuned and ran stock ecu ran fine.

interesting how people can make this assumption without even knowing what compression the motor is.

Try that with a 12:1 motor and tell me what happens.

Depends on whats done to the motor. If its a relatively simple motor , 11:1 and under you can get away with driving it sure, but i would not even think about engaging VTEC until its on a dyno. Just be warned that if the car runs too rich you will get poor ring seal , if it gets too little you run the risk of scarring the cylinder walls.

I dont see how guys build these motors, then dont want to get it properly tuned. You spent money on pistons, rods, bearings, machine work, but 2 hours on a dyno OMG I HAVE TO WAIT TO SPEND THE MONEY!

Do it right or youll regret it. Are you willing to roll the dice and find out?

IMO:
Crank it up on stock ecu, check for leaks, let it run for a few minutes, shut it down, change oil, crank it back up and fix any CEL. At that point if you can afford it tow it to mainstream, if you cant, drive it but be careful and baby it.

Agreed.

Why take the chance after spending all that money? Just crank it up on stock ecu and fix any small problems you might have like CEL codes or leaks. Will also cut down time and money on the dyno.
