MSD

[MrTwinTurbo1988]

I bought a supra with msd. How do I adjust the redline?

 

[Tire Shredder]

you can't

 

[MrTwinTurbo1988]

you can't

I thought you can adjust where your car redlines with msd?

on cars with carbeurators...that is, with no electronic limiting through the computer you can. 7M's ECUs have rev limiters built into their programming, and an external ignition modifier like your MSD cannot remove that.

ontop of that, there should be no need to increase the stock rev limit unless you have some serious modifications. If you do have modifications to take advantage of it, you better have even more to help keep the bottom end and valvetrain together at that speed. Pistons speed is already stupid fast at 6500rpm with the 7m's long stroke.

oh ok. so what good does the msd do me right now then?

multiple spark discharge (more than once per combustion cycle) at low rpm. can give better idle. releases higher voltage, single charges at higher rpm I believe...but could be wrong. In theory it would improve lower end torque, response and efficiency by burning all the gas in the combustion chamber. It would also prevent the spark from blowing out in higher rpm, high compression engines.

However, the ignition system is considered more than adequate on stock and mildly modified 7mges.

it's popular with modified domestics that have old, inadequate ignition systems.

Sweet. Thanks for the info. Yea Im tryin to figure my car out.

I covered a lot of the modifications in the sticky above.

Yea that helped. I think Im gona go back to turbo though so im gona try to sell my N/A.

dont give up so soon! n/a's arent so bad, plus there alot more reliable and def cheaper than our turbo brothers. trust me i own both ive put more money into my turbo than ill ever need to drop into my n/a just getting it running right.

They break down really well

 

[suprarx7nut]

They break down really well

:rofl:

 

[Kckazdude]

That was really cruel. True but cruel.

Did I mention funny also?
