Will do! Thanks much, Aaron!!!

Bill, in Conway, Arkansas

I guess I need to get my 2-step function rigged up on this 6AL-2 programmable ign I have on my turbo car! I am getting more consistent on the lights, but still not great.

I am helped in consistency in that my stall is low and boost threshold is high, so I stage at 0-1 psi. 60 fts suck, but the car is pretty consistent that way.

This one contols the boost based on your inputs. It will allow you to leave the line with virtually no boost and allow you to bring the boost on in a controlled manner that you desire. It will keep the turbo in an "excited" state so the power is instant.

Thanks Tom.

We cobbled up an exhaust system that uses our header, but not the turbo, just for driving to the alignment shop, etc. Freddie drove it on the street for the first time today, and says that carb is FANTASTIC!!! Great throttle response and an idle smooth as silk (and we didn't TOUCH any of your settings!) He says he's sure the car will run in the 14's, at LEAST, without the turbo even being on the car...
He's a happy camper; and so am I.

Thank you so much!!!

I'll check out that boost controller, closely.

Check this out Bill this cleared alot of confusing up that I had

Awesome That is what we needed!!!!!

Aaron,

I read that article, but it seemed to deal with ECU's, fuel injection and digital spark contol, and manual transmission applications (building booos under no load,) none of which our car has.

I didn't see anything that would apply to our stall speed brake-holding problems in terms of random cylinder-disabling through selective ignition interruption, which is how I envisioned a two-step working on a carbureted, conventional (OLD) ignition system like ours has.

What am I missing??? Looks like apples and oranges to me...

Setting up a 2 step rev limiter for a Turbocharged engine

This is where a 2-step rev limiter can REALLY SHINE. Improving your cars 60 ft, and 0-60 times can improve in ways you never thought possible just by setting up 2 step. The reason why is that you can build boost pressure on the starting line, with no load on the motor, by setting up the 2 step limiter with the right parameters. While gaining boost on the line is a plus, you also gain all of the same consistency and simplicity things that we discussed above in the N/A section.

How does the 2step rev limiter build boost with no load

What two step gives you the ability to do, is retard the ignition at a certain RPM to keep the motor from revving higher in the RPM range. By retarding the ignition at a specific engine RPM, we cause the combustion to occur later in the engines cycle. If your not super familiar with a 4 stroke motors cycle be sure to check our article here to help you with this explanation.

With the ignition retarded, and the combustion lagged, the exhaust gas temps ( EGT’s) will sky rocket, and the manifold pressure will shoot up. There will now be a higher manifold pressure and temperature in the exhaust manifold that usually can only be found when the car is under load or at a higher RPM. This increased manifold pressure in-turn will spin the turbine and give the engine boost pressure usually never seen on the starting line. As the timing is retarded even further in the combustion cycle process, the exhaust valve will open and combustion of the gas and air may even occur in the exhaust manifold itself, causing pressure and heat to increase even further in exhaust manifold and build even more boost pressure. This is why when you engage the 2step rev limiter on a boosted car it becomes EXTREMLY LOUD and you hear all of the back firing. Backfiring is when a car doesn’t burn all of its fuel in the combustion process, and then combusts in the exhaust system. The important parameters when setting up a boosted application will be usually ALL OF TH

Aaron,

I read that on their website.

It sounded to me like this boost controller wanted to do two things; retard ignition timing and lean out the mixture. It also sounded like it accomplishes that through an ECU, which we don't have.

How is it going to lean out the mixture on our carburetors, and will it work if the mixture is NOT leaned out? Addititonally, I am uising a Lean-Burn distributor which has NO centrifugal OR vacuum spark advance mechanusm in it, Is that setup compatable with this boost controller?

I am wondering if I can use one of these at all, having nothing on my car that it can control, digitally.

Bill this article is only about setting up a 2 step and the article says there two ways that a two setup works one is to retard the timing and the other is to restrict fuel and yes on a newer car they use ECU but with a application like ours most guys run some sort of aftermarket ignition like a MSD 6AL and run either a dial two step or a pill two step and now msd offers 2 step built into the ignition but I'm sure you already no this Bill
The controller shaker posted the link for if I'm not mistaken is a two step also but you can use CO2 to control the wastegate so at the Christmas tree you can leave the light under load with a gradual increase in boost and traction which will give you them 60 ft times your looking for that is what the topic of the post is isn't it

I have never used a two step or the controller shaker posted the link to and I'm basing this info from the research I've been doing over the last week if I'm wrong please correct me
Thanks Aaron

Aaron,

I do have an MSD 6-AL digital ignition and a 2-step chip for it.

I'll try that.

Insofar as "correcting" anybody (you, included,) I don't know enough about this business to do that... I am just looking for ways to launch this thing... F-A-S-T. All information is welcome, 'cause I have NO IDEA what I'm doing...

Thanks for all your help. I'm getting there.... I think!

Bill
