Frankly, I wouldn't go with either. I don't like the XEDE because it can't compensate for injector dead time, which is needed to get a car to idle and run well with large injectors. And piggybacks are a kludge. And for $1000, it is a very expensive kludge. I don't mind cheap kludges. I do mind expensive ones. If the XEDE were $450, I'd probably recommend it as a relatively cheap system that lets you modify timing and fuel.

I wouldn't go with dynoflash because I need to change my fuel and timing settings while I am in the staging lanes at the track. Without this ability, it is useless to me.

At the moment, there isn't really a good Evo solution for adjusting fuel and timing. What you need is DSMLink for the Evo.

 

Is the DynoFlash going to be offered and performed in other parts (like Works and Vishnu do)...as part of a group dyno/reflash day? Or is it going to be done in shop only in Ct?

 

You guys are advocating removing and installing ARP rod bolts without machine work to keep the rods true?

It seems like you also aluded to other locations at one point, is this a planned venture?

 

If you're not looking for monstrous power over stock... will you
still need bigger injectors?? I want to get XEDE along with
moderate modifications.... maybe that's not even a good idea?

Isn't XEDE a product much like Greddy's E-Manage? Why doesn't
anyone else offering it other than Vishnu?? Competitions always
drives the price down..

 

As far as rev limits and rod bolts I have the following thoughts:

Works has been offering 7850 RPM upgrades as part of their reflashes for some time with NO adverse affects what so ever

There has not been one documented case of rod bolt failure or rod failure that we are aware of

The replacement of the rod bolts using custom tools developed for this purpose has not yielded ANY deformity of the rods - as measured and tested after engine break down.

In the UK - which has had EVO's for some time now - there is no uniform agreement on the issue of replacing the rod bolts on the car. There has been a debate on which is more dangerous - changing the rod bolts and the possibilty of installation error induced failures of various types - OR - failures of the rods.

Personally - there is no clear answer - but for the $40.00 for the rod bolts and 2 hours of labor - to me it was cheap insurance and the bolts were installed with no damage to the rod roundess.
There are those that feel that the rod can be damaged through removal of the rod bolt with the rod in the car, however, I feel that the rod bolts can be safely removed.

If you're only going to go to 7850 - again you will have no problem with the stock rod bolts.

If you want to go to 9,000 you'll need some new rods - like I have - the Pauter ones

 

DynoFlash is the ****

I just had the basics done to my car w/o the dyno... and everything looked great with my datalogger

I cant wait for the dynoflash tune on the dyno.. my car feels so much better with it

It just keeps on pulling way pass 7k rpm but i shifted ar 8k rpm b/c i was a bit nervous... im sure with my boost cranked up to 22 all the way with some 116 octane and -3 to -5% off my safc i am surely in the 11s

 

Hey Al, not trying to highjack the thread, but I have a question for you. I know that you have upgraded to ARP rod and head bolts, but where did you find them and how much? To do the rod bolts did you just drop the pan in place and do them or was the work much more extesive? (I know that Pruven did the work, but you usually have a good idea of what was involved when they do work for you.) Also can you do the head bolts without removing the head and replacing the gasket, or does it need to come off? I understand that the Mitsubishi head gasket is actually a pretty good one as long as you are not going gonzo with the boost, but I would preffer the saftey of some really good head and rod bolts. If Pruven sells them then I would be happy to go through them, I just didn't see them on Pruvens web site.

 

Thanks - good luck on Sunday at the track man ! I hope you had some Mustang road kill tonight !

BTW - be nervous about shifting so high man ! You got to keep them revs lower than 7850 till you get some rod bolts in that bad boy !

 

Something NO piggy back unit will ever have and something that every EVO owner who hits a race track will want - - -

Dyno Flash - Stage REV!

http://www.dynoflash.com/stage2.html


Best bargain in evo land if you ask me !

 

We're going to offer rev raising for XEDE users as well. More info soon to come...

shiv

 

Since I jumped in on Dynoflash, I would say its the best! It offers everything with out the piggyback system. Look at my new post on the Dynoflash. Can not say anymore.

Great idea !I love those extra revs - but PLEASE fellow evo friends get the ARP rod bolts in there before you start enjoying your new found revs. The stock rod bolts will love to strech and strech when you rev and rev. For $40.00 and a couple of hours work its cheap insurance and when you are at it you can see how miserably your rod bearings seated in with the syntetic oil!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Shiv, do you do anything to try and eliminate fuel cut (other than larger injectors, that is)?

I'm interested to hear how you plan on raising the rev limit. A reflash, perhaps?

 

Wait and see

 

I could waste my time and explain how we are handling both features but you'd probably say that it's impossible and that it's all marketing-driven hype. Then you'll continue by saying that the XEDE can't control injector dead time (once again) and that it's a rip-off that should never have been introduced to the evo market. You'll follow up by saying the S-AFC is the best upgrade one can do since ignition control for bolt-on applications is useless and that boost control can be handled better by a Joe P. MBC.

Cheers,
