Nice. Even if your baseline chip gave up 10-15 hp for a safety margin, that would still be a huge improvement over the JWT chip. I am impressed. I should clarify something I said; I don't believe in a mail order chip as the only tuning method but a good chip gives a good baseline to tune from with less correction needed from piggybacks. From those results it seems you provide a much better starting point to tune from.

 

I'm sorry I know JWT has to conservative and try to make the best setup available for a wide band of SR setups, but 40whp/40wtq ... common. Props to Scott!

 

40hp/40ft lbs could be something as little as a degree and 1/2 of timing.. and 1/2 an A/F ratio point on a turbo car. Again, JWT tunes for 91 octane, and they have to be conservative. There's always more power to be extracted.. as Scott has proven here. We do it with stand alones all the time.. JWT is good for a novice person, who doesn't know much of anything about a turbo setup. They plug it in.. and go. And even if they drop a few pounds of fuel pressure... or don't set thier distributor correctly, they won't have to worry about blowing up a motor. Now, for someone looking for optimal power, who knows how to work on thier vehicle, and can have things set up just right.. Sure, tuning for maximum power is what they should be doing.

But as far as the ability of each tuner.. I think both Clark and Scott are great tuners. Clark is 40+ years old, and has been tuning Nissan's for 20+ years. From what I have seen of Scott in the last year.. he knows what he's doing as well.

And, I can see people bieng upset about having to wait for JWT ECU's. No doubt, JWT lacks in that department. However, Clark is the only person who solders/programs out there. The sheer volume of ECU's that they put out every month is unreal.

And I'm sure Scott will attest to how much I defend JWT. Yes, I do.. You guys have NO idea how much help I have had from them in the last 5 years.. Through camshaft development, ECU development, etc.. I wouldn't have been able to accel with the QR25DE projects as much as I have, without thier help.

Again, great job on the tuning Scott.. I'd like to see you and Clark given the same vehicle to tune on one at a time, and look at the end results.

I picked up 38whp from adding a degree and 1/2 of timing and going from 10.5:1 to 11.2:1 when we tuned my S13 (SR20DET). I don't see why you have to say my actions are pathetic... I have been building cars for 10 years my friend.. I know what I'm talking about, and I have dozens of cars under my belt to prove it. No one stooped to the level on name calling before your last post.. I'd appreciate it if you'd show a little more respect, instead of acting childish.

Sure, JWT is conservative. But if you flipped it around, and had Scott (or anyone else) put out the number of ECU's that JWT does.. you would see the same results. The end result.. is that Scott tunes for a LOT of local people.. which is great. He can make the most power on aspecific setup. Yes, Scott does ship ECU's out.. but not nearly the volume that JWT does. I'm sure if Scott sent out hot, perfectly tuned maps to thousands of people.. you'd see a good percentage of blown up motors down the line. And Scott, I'm NOT knocking you.. I'm just saying that some people would get your ECU, that's tuned to the edge for the most power, and have a problem with setting thier timing, or fuel pressure.. and they'd end up blowing up a motor. That's not to say that your tuning is reckless... It's great.. Perfect realy.. but when you get a comedy of errors, and someone who doesn't know what they're doing.. you could end up with a pile of engine parts.

I hope you understand where I'm coming from.. You know how to tune and make great power.. and I totaly commend that. I'm just saying that it's hard to send out a "mail order" chip to the masses, and not have problems if you tune it to perfection.

I shouldn't be in this, but it seems to me that a margin of safety on a given program running at 350+hp should not be 1/7th of the total power. A margin of safety is just that, a margin, so it seems that 10-20hp would be more than sufficient. If the JWT program knocked off 20hp, I'm sure there wouldn't be a thread this long and argumentative. But 40hp, or nearly 1hp per 7hp made bieng dropped off in the name of safety is alot. Really.

I think one thing that you should keep in mind is that each car is a bit different, especially things like turbos and intercoolers. When JWT made their chip the margin of safety on the car they were tuning for might have been 10hp from the peak output. Had they used Enthapys car to create the chip its possible they would come up with a more aggressive tune closer to what Enthalpy created.

The main point is that they have to serve the masses. Between not tuning Enthalpys car specifically and tuning a bit on the cautious side I think they probably still did a good job.

 

I see, so for the more money you'd rather have a 3 month waiting process and make 40hp less ???


I don't think you guys realize how dead on the mail order ECU's that scott sends out actually are.

JR-- and others can attest to that.

And if they blow up their motor? They probably didn't do something right. They probably forgot to list something very important on the list of modifications when telling scott about the ecu. It's amazing how people have yelled at scott because their motor blew up with the ecu in it, only to find out they forgot to hook up their wastegate signal.



You're supposed to list the mods of your car to jwt and enthalpy for a reason, so the ecu can be tweaked to your setup.


If you flipped it around, and had Scott putting out as many ecu's as JWT does, nothing would be different. I don't want to speak for scott, but since he is my room mate i can tell you taht he is very methodical about how he does something. He will spend the same amount of time on each ecu, he won't just give you a batch random generic tune program and say, there you go, off to UPS !

Scott saves EACH and every one of the roms' that he writes, along with dyno graphs of each so that he can compare / contrast / interpolate between the two or more that he uses when writing an ecu.

It's not just a

T3/T4 72# Cobra MAF 4bar fuel pressure program that EVERYONE gets when they go to JWT.

And JWT tunes for 91 octane ? That's their problem then, if they don't have a differnet program for people who live in different states with real gasoline! Why should the customer be like ' Oh that's ok, my car doesn't make as much power because my supposedly custom programmed ecu isn't even correctly mapped for the standard gasoline that's avilable where I live, and practically everywhere else in the united states"

 

not trying to get off the topic but DAMN good number . Sure that car is running a lot stronger.

Yea. JWT didn't care what mods I had. Not even a difference for running their cams.
