quick and simple, i need my FC tuned with it's powerFC and was wondering where you guys would suggest to go in calgary, alberta....

thanx!...

 

The only people I have heard dyno tuning rotary's are lightspeed in red deer and the infamous Max if you can find him!

I need mine done as well...goodluck.

 

Max is currently tending to his family and career. He's a pretty hard fish to catch.

Which sucks because hes perfectly setup to do the job, considering he has a dyno in his garage.

 

theirs a couple of us need tuning done. I suggested getting a dyno day but i don't know how far that would go.

 

I heard lightspeed in red deer can do it, no idea on what kind of tune you get though.

 

With all his rotary knowledge coming from Adam at RX-7 Specialties, you can sorta guess what kind of tune you will get.

 

I've heard the good and the bad come from lightspeed so it's hard to say what the drive is worth.

 

yea i heard it was good, Cory got a tuned map from him, and Cory was easily pushing over 400 rwhp safely.

 

I couldn't find anyone to tune my car, but I did find folks that were willing to help.


I was able to learn the basics of the system I have and I worked off a map that someone gave to me out of a very similarily equiped car. I was accually quite proud of myself when I was able to smooth out the idle and general crusing.

 

Is this the car for sale? http://forums.beyond.ca/showthread.p...90#post2599890

 

no hes not selling it.

 

i asked max and he said he will not tune a car that was not built by him, so i will be giving the guys at lightspeed a call here pretty soon i guess....

 

Safely? Doesn't Cory post under Smitter? Is it really a safe tune if it results in running on one rotor and burning tons of oil?

Just read this thread and noticed that there is a Cory with a blown motor.

yeah that Cory guy posts as Smitter, he took out a side seal in the rear rotor coming back from Manitoba where the air is way more dense. Higher AFRs and knock readings resulted from this. Theres a huge difference in sea levels between MB and Calgary and i drove the car to the limits out there and it finally let go doing 200km/hr pulls, outside of Medicine Hat. It was brutely hot that day to boot. Oh well time and money fixes all rotary woes.
I drive my Fd hard, pushing the boost to the max. Throwing down 400rhwp is hard on any 13b, no matter the tune.

As for Ken @ lightspeed and his tunes, he does a decent job. Come for a ride in my car when i drop the engine back in and c for yourself.

 

There is so much misinformation here it's not even funny. Go learn something about fuel injection and speed density before posting **** like this. What does Manifold Absolute Pressure mean to you? Who's feeding you this crap?

Also there is only a 500 ft elevation change between Red Deer and Medicine Hat. Your engine should not blow because of elevation change.

 

Probably the guy who tuned it.


Gimmie the manual on the Power FC. I'll read it and tune it.

 

Well he probably weakened the seals in MB and then they let go in MH. Use that head of yours... And i believe there is a drastic elevation change between Calgary and MB. And this can create more Cfm and higher Boost because of the denser air. Thats exactly why when you get a PFC, it is recommended that you do not run it hard on the base mod map, because it is tuned for Japans elevation/air density.

We all know rotaries are sensitive, and that just goes to show.

 

So I guess if you get a "safe" tune of your RX-7 from ligthspeed, it really means you are on the razor's edge and you better not deviate from the conditions that were present during the tune? (temperature, pressure, elevation, humidity...etc?) Not exactly what I thought of when I read the phrase "was easily pushing over 400 rwhp safely"

Maybe lightspeed needs to include one of these for the "safe" tunes they do, so you know not go WOT in case the conditions changed too much.

 

So let me get this straight - if I drive my factory original RX7 over the mountains the engine should blow? Right......and Bigfoot will come steal my beer. And weakened seals? Are you shitting me? Seals break from detonation which comes from a poor tune or a mechanical problem.

If he is using a boost controller to control his boost he will see whatever level it's set at regardless of where in the world he is. Modern fuel injected cars use a MAP sensor. It's the pressure in the manifold that matters not outside. So if the car is tuned for 15 lbs it will be safe at 15 lbs in no matter what elevation he is at.

As for the PFC - the reason they don't recommend running on the base map has nothing to do with elevation - because elevation doesn't make a difference. The reason is because every car is different. The base map will get you started but you need to fine tune it to match your engine.

 

Soloracer relax, u always gotta come one here and start calling everybody down, this forum is to help one another out, not discourage people from posting when they have a problem. this **** isnt worth starting an argument over.

since i know u are and educated rotorhead, why is it that i would see higher knock readings and higher afrs in the denser more humid air, are u saying a car tuned here should run safely anywhere? i was even hitting fuel cut in mb when running @ 15lbs,i had to turn the boost down to 12lbs. that never happens here in Calgary?

Its Cam @ Lightspeed (not Ken as i posted before) and he didnt tune my car specifically. i got the map from him that was tuned to a car identical to mine. The car ran great out here with that map for a year. I took it to mb and beat on it, running leaner and seeing higher knock reading on the pfc. it held up through all the punishment i gave it in the east, but let go in Med Hat. As for Lightspeed i am not trying to be a spokesman for the work they do there, i have heard of some mishaps coming out of that shop aswell. Bottom line is how limited we are around here to find some one to tune are cars.

 

is there such thing as a safe tune on a RX-7?

 

Hey Alak, if u wanna tune my car, u could certainly give it a go. i dont think the power fc manual will tell u alot, but i did buy chuck westbrooks tuning notes, and he is suppose to be the man when it comes to the pfc.

 

When I see a post from you with a bunch more wrong info in it I know that no matter what I say you are going to promote your preferred shop who fed you this BS. In your mind anything I or anyone else says is wrong because you believe we have it out for certain people. People used to help others here and they used to post good information. Then came along a bunch of vendor "shop boys" who believed all the BS their shop fed them and the forum become more of a "Shop Promotion" forum than a grass roots community. Anyone questioning a shop was berated and threatened with banishment. I recall some early threads you were involved in where you - without any direct knowledge yourself - chose to blast people because you chose to believe your preferred vendor. Who cares if he's dead wrong. Who cares what the truth is. After all he's your guy and you believe everything he says no matter how wrong it might be. It's stuff like that which has led to the decimation of the self help RX7 community. I know that people got tired of seeing the same shitty work, same shitty advice, same BS over and over again. Finally they figured out it wasn't worth the stress and headaches.

I wasn't even going to post in this thread - in fact I've avoided this forum for several years due to the BS that was going on - but having been in the same situation as Archangel myself years ago I couldn't help myself this time. Now I'm wishing I would have just let it go since I'm getting all worked up again.

I can't tell you why your car was seeing higher AFR's or knocking - I don't know how your engine was built, the condition of the parts used or the quality of the modifications. The fact you are using a base map that isn't tuned for your car speaks volumes. If your shop advised you that it would be OK they should be shot for their incompetence. It was a time bomb waiting to happen. I'm guessing that if your car was tuned properly you wouldn't have had the problems you did. Without knowing what else could be going on with your car who can say for sure. But that doesn't mean you weren't wrong when you assumed that altitude had anything to do with it. Modern EFI systems compensate for altitude. That is why we can drive from Calgary to Vancouver without blowing engines.

 

A properly tuned car that is in good working order run drive at any altitude in any conditions. I tune my own, it drives anywhere and goes to the track anywhere.

What you said makes complete sence. But your always referring to Smitter being "wrong, and believing in what ever his vendor says even if it wrong" That dosent make you any better thinking his vendor is wrong. Its all what people prefer and expect. If you believe a different thing, that dosent mean that your wrong cause its different. Your just was bad as anyone else.

And like Smitter said before, the car was running 100% amazing here in Calgary. i can say it was cause i was in it multiple times, and it would pull like a trane. Amazing. The comment of blowing it in MB because of the alt. was a educated assumption, the car ran amazing here, no faults, then he brings it it MB and on the way back blows a side seal. Thats just a logical educated assumption.

The Map he was running was tuned with his exact engine mods, and he ran it for a long time with out any issues, i doubt it was just the map that caused the car to blow a side seal, maybe it wasn't a safe enough tune who knows. as it was running stupendously here in Cow town. We wernt being ********, Cory was just stating what he believed what happened, and you shot into a rampage.

So seriously if you dont have a helpful post then just sit on the other side of the computer and shut it. And if you think we are wrong, there are ways to go about it, without being a total ***. So i hope to hell with your condescending remarks, and bash talk in your previous posts, that you were expecting some backlash, if not, Check yourself.
