Thread: Big Numbers On SR22VE 20V

Yeah ecu's usually dont go bad unless there is a problem elsewhere. Unless of course its an old mitsubishi. hahaha but even then it was caused by dumb idle air control setups that are powered by the ecu and short circuit causing the ecu to fry. That was just dumb on their part.

But yeah burning up ecu's is not very common and usually not without other causes.

JWT can custom tune your ECU. They will ask you for logs with wideband readings in order to fine tune it for your specific car.

The JWT ecu is good for a basic turbo build. I would say T25/T28 and small T3 based turbos. After spending plenty of time with my brother on the dyno with various turbo setups there is no way an ECU can be plug and play tuned.

There are way too many variables that come into play that make it dangerous to pop a JWT ecu in and go.

For example when JWT makes a specific tune it is more than likely tuned around a turbo other than yours. When tuning, spool plays a big part in tuning the timing map. Under peak load different turbos, different setups will reach that peak a different times. Especially dealing with a stroker motor you may reach that peak and hit a timing load/rpm cell that has way too much timing.TP's are also another thing that varies in the JWT maps. We have had some cars that jump to different TP load scales for identical setups.

When you study and understand the bits and pieces of actual tuning your perspective changes greatly. Again, I am not knocking it as at one point in time many years ago that is what I used, but it is not the way to go for big setups like these today.

Some user error to have an ecu burn up.

The calum/nistune is the way to go hands down. The only advantage of a standalone would be the fine resolution in the timing/fuel maps. A stand alone is not going to make ANY more power on the average setup to about 550hp.

bump for "actual " dyno

Is this the same car that was in the garage when I came to see you.

BS. I made the same amount of power as other guys when I had less mods but with an Emanage back in 2003 when everyone told me to go JWT. You can make more power with a stand alone at EVERY level.

id have to agree, i made 20whp alone using a safc2 a couple of years ago.

for your basic t25 t28 set up jwt is fine.

anything other then that you should spend the money and get a proper engine management.

stratton.

BS? lol ok. Did you even read what I wrote?

I would love to hear you explain how you will make more power with a standalone over a Nistune RT/Calum RT ecu under 550hp+.
