Weldon pumps are obnoxiously loud! The weldon pump controller will help some but I'd really switch to a different pump setup!

All of that is setup by your dealer and you are given a base map to get you up and running! Once those parameters are setup you will never need to touch them. All systems have those parameters, but most systems have them preset in the background and the user cannot adjust them. Is ProEFI...

Please download the new version 3 (V3) software. There are a lot of changes to it! It incorporates many new features like smart logging, meaning if you are in the boost control setup page and start logging, it automatically logs everything you need to set up the boost control etc.

How does the JS system integrate with the ECU? I would certainly prefer that everything is built into one unit. With the ProEFI you can set it up to to pull timing, lower boost, shut off nitrous, flash the check engine light etc with the onset of knock. Also we just implemented the new...

Don't forget about the individual cylinder knock control that ProEFI has. It monitors each knock window for cylinder just for the exact frequency of knock that it occurs at. That is determined by bore diameter and few other things etc. Then it retards just that cylinder. Once the knock has...

Hi Cal, Yes you can run the stock ignition although it would require an ignitor to do so (around $180). Although for as inexpensive as you can buy LS1 coils for now, I usually suggest coil on plug. Because of all the additional sensors that most people add tot he ProEFI it makes it pretty...

Exactly, when you add up everything that you get with ProEFI, it is hard to beat. It would take a $12,000 Motec system to compete.

I am going to have Jason, the owner of ProEFI answer those questions for you. I will forward him a copy of them to his personal email now.

Yes, I just need to get the correct connectors for the stock ECU and ignition module.

ALL standalones need to be tuned on a dyno PERIOD. What self learning does is make small corrections to the fuel map constantly while you are driving so that O2 correction is minimal. Ssometimes it is also called adaptive learning. Short term and long term fuel correction etc. It is...

Yes this is correct. ProEFI also has this as well as adaptive learning for boost control, idle speed and TPS. I just want to make clear to everyone that adaptive learning does not mean self tuning and under NO circumstances should any one assume this.

What exactly do you mean by self learning?? No system should ever be untuned and just let the O2 sensor feedback dictate the fuel map. It should always be put on a dyno first and then let O2 correction make small changes. The ProEFI has Learning ability for idle speed control, boost control...
