looking for tuning advice/data master help

[Sy643]

Anyone interested in helping the new guy out? I am new to the forum and was hoping to find someone willing to look over the data file from the data master software. I have a stock syclone with the basic reliability mods (fpr, walboro pump, plugs, wires, cap) and low miles. Just trying to get the most out of it.
I am located in the midwest (Iowa) so even seeing another syclone is rare... any help or direction would be greatly appreciated.
Thanks,
JJ

I can help you out but Im not a master tuner. You really dont tune with Datamaster either. Its just a recording/feedback only software. I have tuned my stock Syclone off of KR and alky injection to mid 12's according to datamaster. Thats really not the right way to do it. Nolan can tune your truck for $500. He can get you running mid to high 12's without alky injection.
First I would set some goals as far as a budget and use of the vehicle. Once you start modifying it seems like you end up doing three other modifications to make your original mod work.
Send me some files of datamaster to mednetclass@hotmail.com
Do a boost launch and take it to about 110 if you can. I would only do this if your truck is running good. Once I have a log of your full run I can recommend or suggest some things for you. Alky injection is always a good place to start making power.

Re: looking for tuning advice/data master help

Thanks for the quick response guys... I will get my first file out in a few minutes and hopefully get a couple more runs in tonight and send that out as well. My goal is to get it running its best in stock condition, at most add a new (quality) chip for a little more boost.
I plan on doing a second year of bracket racing so I don't have to be the fastest, just consistent.
I am in Fort Dodge, IA and started running a local 1/8th mile and had a blast. If you are ever down this direction they have races every Sat starting about 3PM, $25 for as many runs as you want, bracket races start at 7. http://www.humboldtcountydragway.com/schedule.htm
Thanks again!

Re: looking for tuning advice/data master help

What kinda times are you running in the 1/8th? My truck sounds very similar to yours and I'm curious how times compare. I went for the first time last week and was disappointed. I know one big issue that I need to sort out; just trying to gauge what I'll run. Thanks and good luck w/ the tune...

Re: looking for tuning advice/data master help

Honestly last year was the first time I had ever been on a drag strip and I just wanted to make a few passes to see what she'd do.
Between being a rookie and not wanting break my daily driver I launched it pretty easy. I say all this because my 1/8 mile times are probably the slowest out there. Typcally I will run 9.2 to 9.3 with my best time a low 9.1 on the track. (60ft time was about 2.2 probably not good) With data master run this weekend and a harder than normal launch it showed a "calculated" 8.83 with fresh plugs and fuel filter. I will see this saturday if its accurate. Hope this helps, what times have you gotten out of yours?

I've run mid 7.50s with mine, but that was a slightly larger turbo (20g).

Mid-high 8's would be about normal for a good stocker. Most of it is getting comfortable with the launch sequence. In a bracket environment, a hard launch isn't always the best, as it can lead to inconsistency.

Assuming you have normal radials, run your rear tires at about 21-25 psi and your fronts 6-8 psi higher than that.

Also, stuff a K&N in the stock airbox if you don't have one already, and cut the front cover of the airbox out to get a larger inlet hole. You'll pick up a couple tenths. Wire the intercooler pump to run constantly on key-on, too.

If it's really your daily, you're very wise to not mess with it a bunch. It'll live a lot longer.
I would highly suggest a large trans cooler as a reliability mod.

Been down to Cedar Falls and Tri-State, but not to Humboldt. You're not all that far from Mnpls/St.P, there's quite a few guys in that area. We generally have a track day up here (Sabin, MN) once in the summer, but that's a bit of a haul for you.

There's a guy with a Ty up the road from you a bit in Rolfe. I have a buddy in Tipton that's got a chassis dyno if you ever have need for that.

Re: looking for tuning advice/data master help

thanks for the tips Dig. I have been kicking around adding a trans cooler and I think you just convinced me. Anything brand/shop to buy from? I have used raceprovenmotors.com before, anyone installed theirs?
I have Goodyear F1s on it cause it had the original tires still on it and I just didn't trust the age of them for high speed runs. They seem to be pretty sticky an have worn evenly.
I have a K&N but will definatly try to open up the front of the air box.
Rolfe is just a few miles from the track I think, should tell the ty owner to stop out this summer.
I have a brother in law up in Mankato.... so a trip up north would not be a big deal. If you guys are going to run somewhere let me know and I could try to make it up north eh? ;-)

I don't feel so bad now I ran 8.80s very consistently with a fast time of 8.78. My truck has many of the same reliability mods, hotwired intercooler pump, etc. Only real "performance" changes are a conical K&N to replace the factory airbox and 3" RPM catback exhaust system. I'm running 275/40/R18s that are a tad taller than stock, effectively raising my gear ratio and slowing my launch. My 60' times were 2.00-2.09. The issue I have is my factory brakes. I can't hold but maybe 1psi before it rolls through the lights. If I can correct this prob, sounds like I should be able to leave the line around 5-8psi, drop my 60' times down to 1.70s, and e.t.s in the 8.60s. I hope!

Re: looking for tuning advice/data master help

My brakes don't hold that great either and I have had at least 2 red lights due to it pushing thru and not holding. I have seen these videos of some of these trucks holding with the back wheels spinning slightly and breaking loose off the line and WISH mine would do that. What upgrades are you planning or how the heck are they doing that???

Re: looking for tuning advice/data master help

There's a trick where you shift to N, press the brakes, rev the engine, the brake pedal drops lower and/or bottoms out, keep foot on brake, shift back to D, build boost, launch away. This doesn't work on my truck (obviously).

I can't speak for the faster/modified truck owners, but some common mods I have noticed include: delete the factory ABS, convert to hydro brake booster, upgrade to various Corvette brake combinations.

I too have seen the videos where they sit and slowly spin the back wheels on the line. Very cool, I'm very jealous. I'm waiting for a great deal on a turn-key complete 4 wheel disc Corvette upgrade package to get posted for sale, after I save the $$$.

Sorry to get your thread off-topic! Good luck w/ tuning and datamaster. I'll be learning that stuff soon... :tup:

1st thing to do is the standard "launch maneuver" of pull to the light, drop into N while pushing the brakes down and revving the gas repeatedly (you'll feel the pedal sink a bunch).

Before you go up to make a run, back up on pavement in a straight line, and hit the brakes. This makes the self adjusters tighten the brakes.

As far as mods, the 7/8" wheel cylinders and some soft-compound organic shoes also help. Some guys also buy an extra set of shoes and use 2 long shoes on each rear drum.

Spinning on the line is bad- once a wheel has lost traction, it'll spin more and longer than if it never lost traction.

There are some tracks, also, that are greasy-gooey enough that your front tires skid into the beams. Yet another reason to keep the rears from spinning.

I cut a 1.72 years ago on the original Firestones, and they weren't the best hooking tire out there.

Change your front break pads and rear drum shoes. Pump the breaks a bit to build break pressure. If your breaks are soft, run your truck in reverse and then slam on the breaks. This will tighten up your rear drums. You can also switch to a larger break master cylinder for more holding power.

I looked at your file.
You have bad KR issues at 12lbs of boost. I saw 9.7 deg of timing pulled. Thats a danger zone for sure. Your intake temps reached over 130 deg on your last run (typical heat soaked stock intercooler). Do you have the throttle all the way open? 81.2% TPS is all I saw. You have 20% more throttle to go. No error codes. Thats good. The most boost I saw was 15.5. It also looks like your losing boost as you go if you have it mashed. Your boost control has a lot of spikes in it. Datamaster says your 1/8th mile was 8.7 and your 1/4 mile would be 13.89. Looks like good old datamaster was not so far off on calculating your 1/8th mile. This is typical for a stock truck. If you want to do things the right way call Nolan and get a good tune. Or still do things the right way and get a AFPR and turn fuel pressure up some. That should get rid of your KR at 12 psi. I would try adjusting your wastegate rod or porting the wastegate so you get better boost control. Some times a manual boost valve is a fix but that can be dangerous. If you do have the pedal mashed to the floor get yourself another TPS sensor. If you have it massed that thing is Fed up. Hot-wire the intercooler pump like was said. Looks like you already have a 160 deg thermostat. Thats good. Not really sure if some of this makes sense to you since you are just starting. Holla back if you still have questions.

Re: looking for tuning advice/data master help

Wow, thanks alot guys. I have a list of things to check out tonight/tomorrow and I really appreciate the advice and direction. Hopefully with some tlc, better gas I can get a cleaner looking file sent out.
Now you mentioned this Nolan, not to sound foolish but who is that and what does he do to the truck for $500 to tune it so well? I am very interested if I can keep the truck basically stock and get a huge performance increase. Anything my stock truck would need before doing this?
Thanks again!

Re: looking for tuning advice/data master help

Nolan is the man. All he does is burn a custom chip just for your truck. You can tell him what your target boost is and he can tune the fuel tables until you run out of injector. He just keeps burning you chips and you just keep sending him DM files until its right. Most of his tunes run high 12's on stock trucks. Thats a whole second faster than you are now. BIIIGGGG difference in performance. This is possible only if your truck does not have any current problems. Based on what your datamaster tells me your not ready for Nolan yet. I think his screen name is 10secondTY. You are going to need a 3bar map sensor for his tune. You are running the stock one right now. I can tell this in datamaster. http://www.detroitturbo.com/cart/product_info.php?products_id=66

Re: looking for tuning advice/data master help

thanks rookie, you guys have given me LOTS of good advice and I am trying to PATIENTLY get my truck in good working order ....as quickly as possible . I definately have some work to do and then we'll see if I still have the need for 12 sec speed. lol
I appreciate all the help and the quick responses.

Sorry for come back but you still have the syclone? Still in Iowa? I’m in CB and own a Syclone #0644. Is yours #0643?
