Engine/Transmission (1998.5 - 2002) Why no smoke?

[TXCTD]

I just installed a PM3, JRE cold air intake and JRE 4" Exhaust on my 2002 3500 ETH, How come I can't make a cloud of smoke to save my life? I didn't expect a whole lot out of this set up due to the fact that the PM3 doesn't start dumping extra fuel until some boost is built up, but I expected some.



Also, on there website TST says that the PM3 can be run safely on setting #6 with a 4" exhaust and intake. I max out my 1300 EGT shutoff rather quickly at this level, is that right?



I expect answers from you guys considering you all forced me to start bombing my truck with all this talk.

You will probably need larger injectors before you get serious smoke.

I had the oppisite experience,



i added the comp (ez style) with only a straight pipe,



i had enough smoke to make me worry that something was wrong,



I called aaron at edge and he asked how hot it was in st louis and if i used my a/c, 98 degrees and yes



he said the condenser hurts the intercooler and heats up the air charge resulting in more smoke, and also subsetting 5 has a little to do with it... .

You have the timing bumped with the EZ portion of you COMP attached. Change it to subsetting 1 and smoke will diminish.

i tried subsetting 3 (stock),

and it was not bad at all,



my point was that with ONLY a comp-ez style, that i got more than i expected...



i can't imagine a set of dd3's, that might be a bit much

Thats due to the increases timing... and heat.



If you were to unhook the data plug and attach the pump wire, you wouldn't see as much smoke due to less timing, which is what he is experiencing.



DDIII's... ... . and COMP on 3x3 are not too bad. Normal driving I run with the COMP on 1x5 w/DDIII's

No smoke. You need more fuel. 1300 deg pyro is insufficient. 1500 is better 1700 is about right.

What sort of boost are you making? Does it feel as If the box is adding as much power as it claims? If you are near someone with a pm3 drive theres to verify its working properly.

With the drag comp on max it gets hot in a hurry. 1500 in about 6 seconds.

Im not familiar with the pm3 but it is a major fueling box. I would hope you would see some smoke. If you get dd3s I assure you that there will be smoke aplenty.

Someone I know has the pm3 and the dd2s and he swears by it. Lots of boost. He switched to the drag comp and was not pleased. He lost some boost. Swears the pm3 is faster. I havent raced em but I think Im faster. If a pm3 is faster then you should see smoke cause I see smoke with the comp. Hell I saw smoke with the PNP so who am I to say. I put the drag on kill the other day and punched it for effect. This is what I saw. After boost built I couldnt keep it pointed straight. It put up a 20 ft high smoke screen that blocked two lanes of traffic. Completely obscurring view. No way to see what was on the other side. Now thats some smoke.

I can tell you what's wrong

The PM doesn't do timing. I have a PM2 on my 99 and 275hp injectors and it would only haze a little when I shifted gears. I talked with Mark at TST and he says the PM is a fueling box only doesn't do any timing.



I recently put and Edge EZ on in front of my PM2 (thanks Justin) and man did it ever make a difference. Lots more umff of the line and no more lag at low rpms. And now we have much smoke out the pipe.



I will give up a peace of advise though. The stock clutch doesn't like the extra HP. My cheap BOMB will turn into a $1,200 clutch replacement in a few weeks. :{ :{

Un hook the data plug on your COMP... . and I would bet your smoke level will decrease. You have supermentals so you'll still smoke. . but not near as bad as before. Timing + Injectors=smoke.

Interesting post. I run the Comp at 2/1with DDIII’s. Works well for towing. I noticed that with the outside temps below about 50-60, very little if any smoke, about 70-80 and a little smoke (only noticeable when the turbo hasn’t spun up enough off the line. I was told that the first number is the power setting and the second is to control smoke. I understood that the second parameter adjusts how much additional fuel is added at low boost vs. higher boost pressure. Question – Just what is the second parameter doing? Is setting 3 stock?

EZ or Injectors?

The power I get out of the PM3 is amazing at the top end, but due to the lack of timing, it isn't much at the low end. I was thinking about putting the EZ in front of it, but didn't know if it would have any affect, but after reading up on them, it seems like it would help out. Would the EZ be better than a set of injectors in terms of low end power?



At what EGT temps should I start getting worried if I'm just getting on it around town unloaded? I have the PM3 set to cut back on fuel at 1300. Can I up this or am I compromising reliability by doing that?



Thanks for all the input so far guys.

I kinda have the same question as Aburbach I have a 2001 with a PM3 and it runs strong after you get some boost but it's still sluggish off the start. What's the next step after the clutch install? Do I go with injectors or an EZ for timing?

 

[Steve St.Laurent]

The reason you aren't seeing smoke is because the standard PM3 is a C. A. R. B. approved box. You can talk to Mark at TST and get your box custom programmed to do just about whatever you want. He could program it to add fuel at 0 boost I'm sure. If you add injectors (even 275's) along with the PM3 you will get smoke. I have a custom PM3 that dumps fuel in at low boost numbers (starts at . 5 psi) along with 275's and it smokes like crazy. The EZ box and VA boxes both add fuel at no boost and that is part of the reason they smoke more. Call TST and talk to Mark Chapple about it and what you want. It can most likely be done with the box you already have, he just needs to reprogram it.

$12,000 for a clutch:--) :--)

You wont get much smoke with a pm3,and stock injectors,especially on an HO. From whats been posted here,injectors,and/or a timing box seem to work better on HO's than the fueling only boxes. I opted for the Edge comp,it didnt smoke either,until i added the dd3's,now it smokes like a freight train if i want it to on 5x5,and only puts out a slightburp of smoke on 1x1. Go for some dd2's or 3's,or an edge ez,then it will smoke good.

PM3 Sent back home

Just talked to Greg at TST about having the PM3 reprogrammed to get more low end power, like Steve suggested. Amazingly enough, he said it was an easy job that wouldn't take long and would be cheap. So before any of you other guys with TST boxes install an EZ in front of it, give them a call and check it out. My is getting put in the mail this afternoon, so I will let everyone know what the verdict is when I get it back. Bombs Away

If it would hold 1200 HP and 1800 torque, I'll bet you it would be a hot seller.

Yea, I bet it would.



It's great to be able to send back a PowerMax to have it reprogramed but that still doesn't help when you have an older PM that doesn't have the data port on the back. I have to buy a hole new box to get it changed.

Aburbach after this post last week I called TST and took my box up to get reprogrammed. You'll be happy level 3 is the same as the old level 6. Be warned when I got home with it I raced my friends Duramax burnt him up on level 4,with a slipping clutch. It hurt his ego a day later he was looking at the truck trader for a used 12valve. Better call South Bend I had to.
