My car like everyone else's that is stock has that dreaded no power on top thing going on. My question is for people who have pretty much stock cars and had the reflash done, did it help alot on the big end, a little, how much of a difference did you notice? Would you recommend a reflash as a first mod? I know it will cost more later on to reflash again if I add mods but I don't really intend to mod this car too much, I all ready have a "Hot Rod", just want to fine tune this baby. Thanks!!!

In that case, save your money for cams.

 

The reflash helps more with the more mods that you have on your car. If you do the reflash and a boost controller you'll be strait.

 

I agree to a point but I don't think you need to do all your mods first. You can get a mail order reflash from Al for under $200! with that and a MBC your car will definitely rock! If you get more mods later, you get more dynoflash tuning at a reduced price. I think the basic reflash really helps a lot with the power losses you are experiencing, also, the MBC set a 19-20 p.s.i. will make a huge difference. You are looking at about $250 worth of mods that will prolly get you 20-30 hp. IMHO, it's well worth it and a wise first step to take in the mods road.

 

Thanks Silver, your answer was what I was looking for. i think the other guys didn't quite understand what I was asking. So for me to have a MBC I also need a boost gauge correct? Thanks for your help.

Ya keep it going...... I too want a boost gauge, ont that reads in pounds,,, is the sports meter kit Mits sells any good?

And how esy is it to take off the manual boost controller before you take your car into service? And will they be able to tell if you have messed with or taken it off?

 

Yes, you definitely need a boost gauge. I got a really nice gauge pod for 2 gauges (Greddy electronic ) that goes where the radio went (I've relocated the HU to the cubbyhole location), but I could not install it on time. I rigged up an Autometer mechanical gauge and it's super easy to do and works fine for now (contact me if you want to buy it, I'll make you a great deal on it and the matching EGT gauge). I think the gauge pack is an overpriced POS.
It's easy to remove the boost gauge but the MBC is more of a pain in the butt to install and remove. I only take the car to the dealer for warranty work anyway so it does not matter. For any regular maintenace or other work I'll use good independent shops or do it myself. I hope this helps.

Oh yeah, I almost forgot, whatever you do make damned sure you are using the best gasoline available. From my own painful experience I can tell you that not all 93 octane labeled fuels are good. I had QT gas (very common around here) in the car and it knocked like crazy. It will ruin any mod you make because the more the car is tuned for power, the more knock the shiity gas will induce and the lees power you'll make because the ECU will pull timing to protect the engine................

 

Your in Austin let me help you out some Ill even help work on it. I would not get an MBC! the FBC is more advanced than all but the most expensive EBCs and can control boost based on RPM

 

What's a FBC? my MBC seems to hold boost very steadily and accurately once it's set right.......

 

FBC=frequency boost control, it's how the stock ECU controls boost, through a solenoid that runs off of duty cycle. An even better way is with a stepper motor like the HKS EVC V uses. Nothing else comes close...But I do have an MBC (Buschur) if you want it.

Factory Boost Controller. I agree a Mechanical boost controller can "hold" Boost very accurately at a max value. The Mitsu FBC can control the amount of boost at RPM load points hence you can peak it at 35oo and gradually decrease it toward redline or any thousands of boost combinations you wish. The MBC just pegs it at a boost pressure and holds it there by tricking the wastegate opening. It also cant taper the boost toward redline and if it is its the turbo wheezing out of breath because its grossly out of its efficiency range. Give take people give take

 

Your in Austin also?? Cool, there seems to be a few EVO guys here! We need to get together and go for a cruise or something. I may take you up on that offer! and Yeah, what is an FBC???

 

FBC= factory(frequency) boost controller... Of course, how obvious . Yeah, I agree the FBC works very well and the Dynoflash does change it's operating characteristics.
Still, the MBC will hold boost at WOT and it seems to help the car run a bit faster..... The EBCs are neat and all that, but if all you wanna do is set a max boost and hold it, the simplest MBC will do this practically as well as the most expensive and complex EBC.....

I know that it's not wise to believe everything you read or hear, but the SCC magazine had a comparo of EBCs and a simple MBC back a few months (or years) ago and they found the MBC superior to some, equal to most and practically as good as the best EBD for the purpose of holding boost to a set level.

 

4G63 was more correct than I (Freq) anyway I agree that a MBC is a solid device to hold "peak" boost and it can make more power by holding that peak out closer to the edge of turbo efficiency and near redline. However I bet you understand the desirability of a RPM dependant boost control. Most even expensive EBCs are not RPM dependant and function as a high tech MBC. So again Tit for Tat you straightline the boost with a MBC much like a butchur trims fat from a piece of meat on a steak as you have to tune for the worst case scenereo. with RPM dependant BC you can hug up to max in safe zones and dial back in knock prone areas

Bet you'll like it a LOT ! It really wakes up the stock evo
