I have a Crane HI-6 TRC. The unit includes the timing master controller similar to the MSD 6BTM. This one is adjustable from 0 to 4 degrees of retard per pound of boost. I'm planning to run a little on the advance side, say 17 or 18 when NA for better low end and quicker spool up. As for setting it up to retard, I really don't know how much to set it to. The car will run only 7 PSI of boost. Any suggestions?

 

start at a degree and move down as low as you can get it before you have det. problems

 

I'm thinking about .5 degrees per psi. that's usually a good safe amount. Most people on this board dont even retard there timing at all, some people even advance it.

 

.5-.8 per pound is a good start with stock timing.........

 

Well glad someone brought this up. I keep forgetting to ask about that. Well I just went outside and brought my timing back to stock. I have the d16z6 with greddy turbo running 6psi and so far so good. Little bit easier off the line now. How many ppl are actually advancing there timing? Any problems?

 

I wouldn't recommend advancing timing when you’re running a turbo. You want to just set it either to factory or actually lower. Reason for being is that when you advance too much, you might detonate. And under boost, if that happens, you're pretty screwed if it's really bad. The reason why I will advance my timing is because I have a unit that will automatically retard timing when I'm under boost. That way when I'm naturally aspirated, the car will have better low end torque and quicker spool up. But when I hit that first pound, the unit will retard it whatever degree I set it as, and will keep decrementing timing per pounds of boost.

 

I would recommend the Jackson Racing BTC, even for a turbo car. it works much better than a btm or something similar. it actually changes the timing curve and you it adds timing in the top end where it's needed. I'm currently running 5.5 psi with timing at 18 degrees on a b18c5 with only the other stock JR stuff.I have no detonation and have a safeguard to monito these things. I also have the JR MAP controller.

 

daym.. i got mine on stock. no retard at all... that a bad idea? hehe im only running 7 lbs.

 

I don't really know if it's that bad to keep it stock at 7 PSI, it's probably OK. What you would NOT want to do is advance it. The only reason why people retard it, is just to be on the safe side when at WOT and running higher boost level. That's when engine can blow and with that few degrees of retard it'll help to keep the engine from detonating.

 

i jsut got my btm in, so how can u tell when its good? i'm running about 6psi on the street and 10 at the track.

thanks

 

Stock on a honda (mine, anyways) is 12 degress advanced, or, 12 degress before top dead center...thats STOCK setting.

If I run a 5 degress retarded Im running at one 7 degress advanced (12-5=7).

Running a turbo engine at stock timing is VERY DANGEROUS as detonation will likely occur.

MSD BTM is a GREAT way to avoid this,or similar products.

RUnning a stock timing is NOT a good idea.
