As the topic says. Also, i am running hondata 4b so will i need an ignition that supports timing retard under boost? Theoretically i wouldnt think I would since the hondata controls the timing retard. Im looking into the msd digital systems...

 

my beast uses the crane, if only i could make some horsepower...

my goal is 400whp this year am running msd 6al with 3step and blaster 2 coil and msd wires

 

You dont need one that retards the timing under boost. Your map should be set up like that with your hondata. Some people retard the timing .5deg for every psi, while a more conservative tune will retard it .7deg/ psi. Im just gonna run the MSD 6A since the AEM EMS has a 2-step rev limiter.

You dont need anything else for your ignition retard except the Hondata program itself. If you want to upgrade your ignition go with the MSD 6A (the basic one you dont need anything else), blaster coil, distributor cap. I got the wires since i wanted to keep the entire ignition system consistent.

 

Just a random question guys, as some of you may remember i had a crane hi-6tr installed on my car after my hondata was tuned. After the ignition was installed i melted a piston and blew a headgasket. No changes in timing were made. I spoke with crane and they said it was not needed to run the TRC unit if i had a standalone monitoring my timing controls. Any inputs on this?

 

Hmm sounds like you were running to much timing if you blew the headgasket and melted a piston. Just a guess though. Perhaps the timing retard unit was doing the opposite of what it was intend to do.

 

actually the TRC was never hooked up, crane specifically told me i could just install the hi-6r unit and i would be fine. Do you by not running the trc on the ignition it added too much timing?

 

Yeah blowing the headgasket and melting a piston usually means that you detonated pretty bad. That would mean one of three things: Your timing was to much, your air/fuel was to lean, or you got a bad tank of gas (your octane level was lower than what you tuned the car on).

 

Anyone else with the MSD 6a?

 

motec cdi.....yeah when I hit this lottery up here in rhode island.
I run the msd dsi ho used to have the dig 7 programable. but
I think the best for your setup is the dig 6.-pdang

 

Not enough timing can also cause detonation, which could cause the same problem. High EGT's too...

 

Speedpro, MSD 6AL and blaster coil here.

 

I'm running the MSD digital 7 plus but i'm sure the digital 6 plus will work fine also. i'm making over 550whp with the digital box and havent had a problem yet. the msd 6al was getting interference with the hondata and caused the dyno to go wack too. switched to the digital box and everything was fixed.

I'm sorry i did not mention this earlier, but the hondata was fully tuned. The a/f ratio was bw 11.0-12.0 averaging roughly a 11.6. I told the tuner an ignition system would be added in the nearby future so thats why it was tuned a little on the rich side, since the ignition would help to burn fuel more efficiently. As far as timing, all the ignition values were programmed into the hondata. Despite crane and numerous people telling me it would be perfectly fine to run without the trc unit and any further tuning, after the ignition was installed the headgasket blew and the piston melted.

Very good point. I actually monitored my EGT's while i had this problem and it stayed pegged at 600deg on my greddy gauge under heavy load. While highway driving it would sometimes jump up to 700deg though.

i'm runnig the MSD SCI, which is actually the same as the 6A ignition, using a Blaster SS coil, and the stock cap, since our cars alreay have external coils, you won't need the MSD cap

 

I'm running an MSD DIS4 with an Autronic SMC ecu on my S2000. I ran the same setup with individual coils on my boosted H23 before I built the s2k motor.
