Nismotronic vs Enthalpy/ JWT

[Loomis112]

Haven't really seen any posts discussing this. I was wondering which would be the better decision with the two?

I know that Nismotronic is pretty close to the stand alone level where as the other forms of tuning such as JWT/RS are just ROM tunes.

Both JWT/RS will cost you about as much as the basic Nismotronic package

But then again you have to find someone to get it tuned, on the other hand the ROM tunes are tuned by the pro's like Martin.

Read the thread about Rs-Enthalpy and you'll decide real fast :)

I see that lots of people like the Rs enthalpy tunes but I don't really see a side by side comparison between the two.


I haven't really even seen many dyno graphs of user's using Nismotronic on Zilvia at least.

I'm curious to see what someone whos used both methods of tuning has to say about it. (I know they're both great ways to tune I'm just curious)

Enthalpy gives you a tune you just plug and play. Not to mention the fact Martins service is the best. He'll answer questions and has knowledge to offer suggestions based on his experience. Thinking about changing anything? He can tell you what gains you can expect, what you may need to tweak, what can be left alone.
With nismotronics you have a lot more parameters and better control... But you're still going to have to find a tuner to tune it which will probably cost a few hundred on top of the money you spend on nismotronics. Unless you go their e-tune route which I'm sure is okay but something about remote tuning doesn't sit that well with me when trying to maximize your set up.
I'd be willing to bet Martin has probably tuned more Nissans than any single other person.
Shoot, if I got nismotronics for the extra features I'd still want Martin to tune it anyway.

This is more a question of whether or not you can tune a car, or are willing to pay for a tuned ecu/tuner..

[jedi03]

Plus one for enthalpy...even second hand his tunes are awesome! However I got mine done diectly, his knowledge and troubleshooting are amazing!

@OP you aree trying to compare ready made food (mail order tune) with an oven (nismotronics).

And you just can't.
Getting a ready to tune ECU means you need to know how to tune, or have someone do it for you. You also need various other bits to do the tune (wideband lambda, EGT sensor, knock eventually)

A mail order tune is still a generic tune, it will always be on the conservative side. Better than nothing, yet worse than custom made (although sometimes not by much)

I know which one I'm going with.

Nismotronic.

So much more expandability.

Found a used PFC the other day for $350

honestly you cant beat that for a standalone. Keep your eyes open and snag one off ebay.

[Bleakley]

PFC's are going at a great rate right now. It's def something to consider. Power FC with datalogit and your off. Hell, I'm sure Martin would help you, I'm pretty sure he has something to get you started and then there's a way to pay him to help you with that. He is undoubtedly the f***ing man when it comes to him and his customers. That much is obvious. If, for some reason he can't help you with the pfc, hit up shadowerks. I say go with Enthalpy for now, and then upgrade (if you consider it an upgrade) down the road.

Pretty sure you can datalog and send it back to Martin and he'll dial in your setup even better. I aware I heard that talked about..

Bottom line, YOU SEEMINGLY CAN NOT POSSIBLY GO WRONG WITH MARTIN AT R.S. ENTHALPY.

[Kingtal0n]

you dont need a data-logit to tune a MAF car with power FC. It can be done in a couple hours easily, yes with the commander and efficiently at that. The basic concept is to use the maf to your advantage- since it goes directly after VE (maf voltage -> cylinder VE) you can plop one single constant across the board (one solid line of identical fuel values with minor tweaking for peak torque areas) and then use the airflow meter's global percentage fueling (fuel % per maf voltage) to make instantaneous changes to your air/fuel ratio while driving. Within a few minutes of highway driving you can have your WOT tuned in good enough to hit the dyno, and finalized in 1-3 passes at one single boost level.

Timing values come from experience and datalogging of variables. I have provided a map recently in one of my posts that will work for most nearly stock sr20 powered daily drivers, in fact.

There are no longer many secrets. Everybody (should) knows 11.8:1, 18psi, 93 octane, 9-10* btdc, stock engine / stock turbo is nearly 280rwhp with PFC "knock counts" below 14 for a 7000rpm pass.

Then there is cams, headwork, larger manifolds, larger turbo, perhaps a touch more compresion, and guess what? Still 11.8:1, 18psi, 93 octane, you might pick up an extra degree or two (10-12* btdc) and the result is always around 380-410rwhp (sea level, accurate gauges, dynojet, 0 smoothing). Lighter cars (and thus, lighter dyno rollers) will see increased power output with more timing (often 13-15* btdc for peak numbers to appear on such rollers) but this is not acceptable timing number once the vehicle hits the street, and it should be reduced (back to 10-12 on all but the lightest of track cars featuring sponserships and requiring absolute performance at all costs).

these engines have surpassed all expectations of " cookie cutter " status. Our next step seems to be reliable procedures for rebuilding the stock engine without the help of a machine shop (eliminate machining errors would be nice). This is where I will direct my attention when I get a nice break.
