msd ignition and high compression need help deciding

[Devin]

i read lot and lot about this being grate for turbo and superchared apps but never high comp cammed out engines,i have a fully built 12.1 comp cammed out stroked big bore h23/f22 frank with stock igniton i was thinking of upgrading to a msd digital sci ignition mod. num 6350 and upgrading to a external msd blasterss coil extreme cap and rotor and custum wire set should this cause any ecu tuning issues is it a good idea will it help me at all or should i leave it alone. Just need a little advise from the cb7 pros

In my opinion the msd is not really a necessary mod. I think it helps the higher your rev your motor. For a stock application where you're not gonna reach anything higher than factory rev limit then msd is not necessary. If you're planning on going to 8500 -9000+ then i think the msd would be somewhat helpful. Not to say the stock ignition cant do it but i think the msd smooths out the higher rev range.

With your mods and compression, the MSD ignition will definitely help.

I would guess it would too but i know many peeps who feel the honda ignition is the greatest thing since sliced bread for all setups but me personally i love my msd.

The Honda ignition is fine for mild setups. When you go boosted, juiced, or using big cams and crazy compression, it's better to have a stronger spark. The MSD stuff is also a bit more versatile in terms of tuning. You have more control if you get the right things.

This guy's setup could benefit from a stronger ignition. Your setup, Chris, would probably be ok with the stock one still. Regardless, having the upgrade doesn't hurt (we talked about that at Honda Day, I think... I'm usually the first to say "you don't need that!")

Does MSD make a direct ignition system for the F and H engines?...I wonder if its worth the effort?.

[deevergote]

Direct ignition, as on the new VW engines? No, it'd require major modification of the motor to do so.

Coil on plug, perhaps. I'm not sure if MSD does it, but it's definitely possible to make such a system.

If thats the case then ill be needing it for sure by next summer!

Im gonna take that chance and build my head.

Whats the power your gonna make? Stock ignition systems usually can take up to 3-400 hp from what I have seen. The weak part of it usually is the coil. That I would definitely replace.

[Devin]

thanx guys but my real question is will this sytem cause me any tuning issues because they go in and change my curve and adv and retard and such will the tunning still be possible does this unit still depend on my ecu or is it a stand alone type system or will it give me an advantage durring tunning

[NAiL05]

It will be tuneable. The ECU tuning is separate. I know there is an MSD box or something like that that allows a two step and other stuff. Some people have experiences with that but I am pretty sure you can program thhose into the ECU.

There are people running over 600whp boosted setups with the stock ignition.

[deevergote]

I didn't say you HAVE to have a better ignition... but it's better. More control, more accuracy...
