can someone tell me the difference between DP-tuner 80e and 80t - Diesel Forum

clydesdale · 12-13-2006, 12:40 PM

I ordered the 40t 60t and 80e. While waiting for the new cable, I am starting to wonder what the deal is with 80 tow. Is it stonger and less fuel efficient? Is it a daily driving program? What's your thoughts. Thanks

Ask Jody if you want a definative answer, but I think for all practical purposes, the difference is in the shifting. I think the 80T has a little less tip in on fuel as well.

clydesdale · 12-13-2006, 01:39 PM

I have a manual trans. I will probably give him a ring. But I wanted to also hear from some users. Thanks

oops, this thread should be in the aftermarket section. Can a mod bump this over?

Done

I have Jody's 80 econo flashed on a PCM, and first had the latest version. It was WAY touchy in the lower gears and the pedal tip-in was pretty extreme. Driving it in traffic was real hard on the u-joints with the bucking I was getting. I had to drive it with the proverbial egg under my foot to keep from bucking too much.

Traded it in on Jody's "Classic" 80 econo tune, and it's very nice. It's my daily driver, and is quite manageable even on slick, icy streets.

Don't know the difference between it and the 80tow program, but if 80t is more agressive on pedal tip-in, I think I'd avoid it with a 6-speed for daily driving. Might be fine on a multi-position chip, though. ON EDIT: I see I got that backwards. It was stated that 80tow is LESS agressive than 80econo. Yeah, call Jody.

I have Jody's 80T flashed into my PCM. I also have the manual trans and I've just learned how to shift with it. I like the power but I haven't checked the milage yet. I will on Monday as I drive from Florida to Illinois. I like the power, it comes on hard and fast even at low RPMs. And I think... that's the difference between the 80t and 80e. The power comes on at lower rpms on the 80t.

If this is the case then I'm in on this. I get the same fuel mileage with the 60tow and the 80econo so unless MPG goes down with the 80tow I'm in!

I forget the guy's name on here but there is a guy in Hawaii that runs the 80tow quite a bit - hopefully he finds this and chimes in.

I was told, when I purchased my F5 chip from Beans, that the difference between the 80T and the 80econo was timing. The 80T doesn't heat up the EGT's quite as quick, while towing, when compared to the 80econo.

At least that's what I was told.

I explained to Jody that I wanted all the decaf versions. I am looking for a smooth linear pedal. But I guess I am thinking maybe I may want one of the tunes to be a little stronger. I don't want to go into the 100hp zone because of my pmrs. But maybe 80t will have some good punch. Hopefully someone with 80t will chime in. Thanks

clydesdale · 12-13-2006, 11:14 PM

firehunter, what are your thoughts on the differences between 60t and 80e?

FireHunter · 12-14-2006, 12:40 AM

Well, first of all I am not a drag racer and I am not looking for max HP so the 60tow has always been my favorite program for all around use. I started with a 60tow PCM and then got the chip later with 40tow and 80econo. While I had the stock turbo the 60tow made all the power I could ask for while empty or towing and if I really got after it I could get the clutch to slip. With the stock turbo the 80econo had two different personalities and drove more like a light switch - either lagging badly or making a ton of power with very little in between. Between drivability issues and not seeing a significant MPG increase I drove 90% of the time in 60tow and had/have no complaints. The 60tow was Jody's original reccomendation to since I could only afford one program at the time.

Now...I have stated the above quite a few times on here and need to add to these comments now since I have this van turbo. This turbo has made ALL the programs, including the 80econo, very smooth throughout the power curves with no sudden changes anywhere. Others with the van turbo have reported the same thing - smooooth power everywhere. I can now use the 80econo as a daily driver program, except on slick roads, and I can even tow with it and not have to back out too often. Unfortunately, I am still getting the same MPG with 60tow and 80econo. I was hoping for more but I am satisfied with 17 - 18 and the kind of driving I do. The engine makes significantly more noise in the 80econo and I attribute that to the advanced timing that Stewart mentioned. I ALWAYS start a cold engine in a tow program then switch to 80econo only after it's fully warmed up. Call it superstition or whatever, that's just what I do.

I would like to try the 80tow and even the 100 or 120 programs but don't see a big reason to until after I replace the clutch since I can get it to slip as it is now.

I only use the 40tow this time of year when it's very cold, sometimes below zero, and slick roads. Otherwise it's mostly 60tow with 80econo on the open highway.

I do not know the technical difference that Jody would be able to rattle off. He is the MAN for tuning and he would be the one for the techie. However I can tell you I have both 80T and 80Econo. 80Econo has a very rapid dump of fuel to spool the turbo. This keeps the TC locked with a lot of boost happening making the exhaust HOT. It is great empty but with a load the EGT's climb rapidly and the shift seems a little firmer. The 80T is very smooth and allows you to have throttle finesse yet the power is still there when you mash it to the floor. The EGT's take a while to get up there but you have lots of power and I tow a lot of miles a year. I use 80T around town in the rain. But if some ricer is near or another oil burner I switch it up to 80Econo or 120race. [img]/ubbthreads/images/graemlins/grin.gif[/img]

clydesdale : I do not see that you have exhaust upgrades. Is this true? [img]/ubbthreads/images/graemlins/shrug.gif[/img] If not you would want to do that before the chip.

clydesdale · 12-14-2006, 07:47 AM

No exhaust yet. I am going to do the chip first and see what the egts are like. Also, it will help me experiment a bit. I also ordered a stock setting. So doing it this way I can tell what just the chip does for economy and then when I get an exhaust in the spring I will see what just an exhaust does. I will leave the truck in the stock setting for a few tanks to see. Then I will switch to both chip and exhaust. If I throw the exhaust now, then I won't be able to determine what the chip alone does for me. I do have guages and will watch closely.

Firehunter, do you get the same economy on 80e and 60t even unloaded on the highway? Is there a noticeable power difference between the two. Thanks

Yes. I made a run across Idaho (SRV) in 60tow and averaged 18.1 MPG. I made the same run in 80econo and averaged 18.2 MPG. This was with the same load in the bed which was ~500 lbs...basically empty and not towing.

While towing my 4H GN trailer I get 12.5 MPG in 60tow and 12.0 in 80econo.

Yes and no. As was mentioned in the previous post, the difference is in the power delivery and yes, there is a noticable difference in delivery. As to max HP/TQ measured on a dyno there really wasn't a big difference IMO. EDMGUY ran a bunch of these settings on a dyno and posted the results but I am at work and they are at home so I can't quote them. I remember the max TQ was less than 50 ft/lbs difference between the two which confirmed my SOTP dyno. There will be a bit of apples and oranges since both EDMGUY and I have turbo and exhaust mods but the results should still show you a "trend" to help you decide what your looking for.

clydesdale · 12-14-2006, 12:12 PM

That dyno chart would be great. I have a little while til the new f5 chip cables arrive, so i can modify my order if necessary. I have thought about just adding the 80t on top of my 40t,60t and 80e. Thanks
