Do I need to get my ECU flashed before adding the ECU+ to remove the stock settings such as the rev limiter?

Also, it seems like ECU+ can control cam timing. Does this feature serve the same function as cam gears?

I'm really new to all this, and I want to get into tuning my Evo to squeeze as much power out of it as possible. From what I've read, it seems like ECU+ is the way to go (as far as features and cost). Is it really easy to learn how to tune your car? Are there safety settings added so that I can't completely destroy my car while I'm learning to do this? Any other advice?

 

you can ru it with the car flashed already and overide it with the ecu+. Luckly my dealer mod friendly and flashed my ecu back to stock for me free.

 

A mail-in flash is handy for two things:

1. Getting better driveability with large injectors. (700 and up kind-of range)
2. Raising the 7x00 RPM rev limit.

No. Cam gears adjust where the cams open and close with respect to the engine cycle. The ECU+ timing adjustment moves when the spark fires in the engine cycle. These two are two different things.

I'll let someone else talk about cam gears, but it seems like most of the people who have them haven't actually adjusted them beyond 0 degrees, so I don't know how much use they get.

I think the ECU+ is one of the easiest systems to use. (Hell - what do I know?) But you can definitely destroy your car with it if you don't go slowly and carefully. If you're skittish, you might want to get some professional tuning on a dyno. While that's going on, try to understand the process and then use that in later tuning sessions with the ECU+ (say, after adding another part, or tuning for race gas). But by all means, get a wideband O2 system to go with the ECU+. That's your best investment for safe tuning.

Tom,

what about needing a flash to eliminate fuel cut? On your website it says that the ECU+ has a "fuel cut defender", how efffective it this? At the moment hitting fuel cut is my biggest problem.

 

there is a feature that will help you stay out of fuel cut. It has a maximum maf frequency output clamp that you can set.

also, cam gears just basically move the powerband around. the more you retard the cams the more you sustain your torque over rpm. The more they are advanced, the more quickly the torque drops off, but its a double edged sword. If you retard the cam gears, you dont get a huge torque spike like a stock evo does, it's usually just a very very flat torque line.

 

This feature works, but almost no one uses it. The reason is that fuel cut is calculated in the stock ECU based on the MAS frequency that it sees. With a device like the ECU+, you end up decreasing that frequency to compensate for overly rich mixtures or larger injectors. So, the fuel cut problem just goes away on its own and you don't need to worry about it.

I completly understand what your saying, however with the SAFCII I'm now using to tune, I'm getting fuel cut in the lower RPM (~3,000-4,000). I can't take away fuel because its already lean to begin with and if I try and add fuel I'll just wind up maxing out the MAF frequency that much sooner.

Will I run into this problem with the ECU+?

 

What turbo is on the car? What injectors? And what are you defining as lean?

BTW - for the information of those using ECU PLUS

Dyno Flash offers a reduced price base flash at $75.00 which is of use to those using ECU-PLUS

It offers the following features

1 - rasies rev limiter to customer reuqested spec (7800 suggested)

2 - removes factory fuel cut 100%

3 - fixes high and low octane fuel and timing maps so the stock ecu does not switch back and forth altering your tune

4 - Scales fuel maps for specified injectors and alters injector battery response time scaling for commonly used aftermarket injectors

and

5 - soon to come two step rev limiter

This flash is not listed on my web site but is available by special request

ALL ECU PLUS users shall also recieve FREE return fed ex shipping with their purchase of this flash

Finally - I offer custom tuning on the ECU PLUS which includes a tutorial for the customer on general tuning methods for $200

Thanks

 

Folks - this sounds like a good deal from Dynoflash, and is a good example of two sorta-competitive products working together to provide capabilities that either alone can't offer. In this case, the reflash gets you improved drivability with large injectors, and the fuel cut and rev limit removal. The ECU+ then takes over to provide the datalogging and fine (or race gas) tuning that the Dynoflash can't offer.

Thanks for posting this Al.

(BTW, this offer was news to me, and is direct through Dynoflash; neither Mach V nor myself have any actual involvement with Al's reflash services.)

ECU Plus just gets better and better.............

Looks like the ECU goes to dyno flash to get the ECUPLUS FLASH when it's in the shop as soon as I get home.

 

That's very cool Al, I'll be hitting you up here soon, for more info.

Jester has basically the same deal going on for a "base flash" to remove the fuel cut and raise the rev limiter.

that is who will be getting my business

 

Please, Nothing With Dynoflash!

 

WOW! AL When is that 2 step going to be ready?!
