My car is kaput, 86'd, k.o.'d, done for, down for the dirt nap...thats right...it's ut of commision. so I plan on rebuilding it. id like to go ahead and get an aftermarket ECU, any suggestions as to which one is best? how about bang for the buck? Any help here would be greatly appreciated!

I would like to know which is best bang for the buck too.

It all depends on which features you like. I think that the new Wolf 3D 4.0 will be a really good buy because it comes with a boost controller.

Note that installing and tuning an EMS isn't all that easy, even with the Wolf which doesn't require a laptop or dyno like most other EMS units. I recommend looking for an EMS that your local Mazda-smart speed shop will sell you in a package deal that includes installation and tuning. It will be more expensive this way, but not as expensive as a blown motor. Be careful on what kind of "bang" you get for your buck.

go haltech e6k, there is some much surport for these on rx-7's. and they do everything you need it to do. including boost control as mentioned above. you just need to buy another peice. I just got my friends running yesterday with it and it wasn't very hard at all. you just find a base map on the net which are everywhere. there is little surport for the wolf.

theres actually quite a bit of support for the Wolf out there. but the E6K is still a better computer. and the boost control setup for the e6K sucks..........you are way better off buying a profec/ AVCR/EVC etc etc.

im not sure if hes askin about standalones or aftermarket chips tho. if you are inquiring about chips, only a few are really available for the FC here stateside. and assuming you are not running crazy boost on a big turbo, a chip can work great for you.

also, a lil shameless plug here......if anyone is interested in a chip i have a complete Knightsports ECU for the 89+ TII. its good for 15psi, no fuel cut or rev limit, modified ignition and fuel curves etc.

How much is the E6K with the boost controller?

There is actually a lot of support for the Wolf, but local support is very difficult to find in the US. Haltech is much better in this respect.

The Wolf 3.x shipped with a base map which was quite capable of initially running every rotary engine that my local dealer has tuned. I'm sure that you can get plenty of base maps for every other brand of EMS, too, but to think that someone else's map will run your engine safely at high loads is a venture into folly.

Ive heard a lot of good things about the haltech, does anyone know of a web address where i can read some more about it...including a PRICE!

try haltech.com or .au

you are basically looking at ~1200-1300 on oaverage for a haltech, plus the labor of wiring it up and pulling all your old wiring harness and ECU. its not THAT much work, but its definately not a plug and play kinda thing. we installed mine with a full days work.

not sure about the controller. it's a GM add on part. my friend was just about to try and find one.

I was refering more to getting the car started and running with the map. the car runs and drives perfect off the hitmans map. it'll definatly get retuned once the engine is broken in and running boost.

Where can you get an E6K for that price in the US? Pettit sells them for $1,900. I don't know about that GM part, but a boost controller like the AVC-R sells for $450 at the RX-7 Store. That all comes out to $2,350 vs. the $1,300-1,400 for the Wolf3D 4.0 with 3D boost control, hand controller, and wiring harness. Although the new Wolf wastegate solenoid hasn't been priced yet, it still has to be cheaper than the Haltech setup. I will agree that the Haltech is very nice, but this thread was all about the "bang for the buck", right?

West TX RX-7

Be fore warned. You should get an upgraded turbo before trying to make boost adjustments. The stock turbo has a very small wastegate that doesn't respond correctly or consistently to boost adjustments. Small as in the size of a penny, an aftermarket turbo with a 40 or 50mm wastegate will work much better.

I run a factory turbo with an intake, exhaust, duel belt underdrive pullys and a good tune up on the dyno and am getting a healthy 218.8 HP to the ground. It is plenty quick and as reliable as you can get. Before you go spending several hundered on a controler be sure you have enough cash to go ahead and get the motor and turbo's built up enough to take advantage of it.

~2 cents~

i was being a bit generous on the pricing actually. a haltech is nowhere NEAR 1900$. i actually paid 1000$ US for my E6K, 3 Bar MAP sensor, and harness, all brand new.

i believe they are doing another group buy here on the forum for them. at any rate the E6K is cheaper than the Wolf, but you will need a cheap laptop to run the E6K, and i mean cheap as in like a 70$ laptop off ebay will run it.

Evil Aviator

Hehehe, I figured that Pettit would be more expensive than average. Hey, I found the Haltech MSRP for the US on Hitman's site. The E6K with options comparable to the Wolf (minus hand controller, of course) would be $1,532, which is only about $100 more expensive than the MSRP for the Wolf3D 4.0 + software package. The E6K boost control solenoid is listed at $80, so we will see what Wolf will charge for theirs. Hopefully, the Wolf boost controller will work better than the one on the Haltech.

Hehehe, yeah, you will NEED a cheap laptop for most of the aftermarket EMS units because they usually only work in DOS. It will be nice when the Halwin software finally hits the market.

i dont have any direct experience with it, but i hear the boost control solennoid for the E6K kinda sucks from others who have used it. ill stick with my profec B
