I just read the thread that said that xs will not be free to dyno tune cars for two months. I was told that they would be up and running by next week and am ready for the tuning this week....apparently xs is not ready.

I need to get my car tuned...I purchased the pfc from the rx7 store and because of miscommunication from the use of the middleman, it did not come tuned to my specifications.

Currently, I limp around like a gramma out of fears of running too rich or too lean with the large injectors and all the mods. I just want to drive my car. haha

Well..now I have it installed....got my mod list up and ready for the tuning and even went as far as getting the m2 large intercooler so that I can help keep temps down on the dyno.

THE PROBLEM...is that I cant get on the dyno and xs has a local monopoly on the software to do it.

I have four options it seems....

one, I can find someone with a mod list closer to mine and get their maps (unsafe in my mind)....

two, I can wait two or three months til xs is ready to do business. (no way Im waiting all summer to drive my machine)

three, I can find someone local with the datalogit and wideband and beg for help with the tuning! (Im not knowedgable about this and have concerns)

and finally, I could sell the brand new pfc and get a haltech and find someone local to tune it on a dyno. (time to start researching the haltech)

WHAT SHOULD I DO?

I would appreciate some input....any at all.


thanks

Hey Jason, sorry to hear about your tuning problems - that sucks about XS, i know you were looking foward to getting that beast tuned as were a lot of us. Problem with taking other people's maps is not everyone on the forum has mods like yours (M2 twins) so your maps would be different than most everybody elses who's running the typical full exhaust, intake and IC. Might want to think about having SR Motorsports tune it temporarily until you can get dyno tuned by XS but I still wouldn't push the car until you get on that dyno with their software. Haltech's are awesome but are a complete pain to install from what I've heard. Hope you figure something out.

ive heard bad things about running base maps... I would avoid that!

Jason, There are base maps for your set up here on the forum. They would probably be ok for normal driving. Go to the ecu section and pick the maps that resemble the closest to your set up. I would not beat on the car until it was properly tuned as you could pop your engine. I would wait (2 months is not long) or try Tri-Point or call Rotary Power, ask Jeff Mccaul if he can help or refer you..

artguy

thanks guys...

rotary power cant help me...I called them already.

tripoint cant help me...I called them already. they deal with haltech and motec only.

xs is the only crew with software and they are way too busy with their move.

you are correct...no one has the same mod list...someone today told me I had an odd duck. haha...yes I do...hopefully a beautiful swan very soon.

I have two options..one is sell my pfc to someone who doesnt need to dyno their car and get a Haltech which the pros are suggesting....or two, drive seven hours to see ray at srmotorsports for a day or two.

Im considering the drive...Ive had a few great conversations with ray and I trust his knowledge.

I will try xs one more time tomorrow or tuesday...if they cant help me Ill go elsewhere.

My advice to those wanting thick mod lists...dont use the pfc...tuning it is a pain in the...

the haltech is a pain to install..but possible to do....from what I have heard.

the pfc is easy to install and a PIA to tune if you have a longer mod list. It probably would have been easier if I didnt try to do quite a few of the mods and the pfc at the same time.

What about option 3, get a datalogit and tune it on a dyno. It (PFC) has settings for your larger injectors and non seq turbos. The base maps should be fine, but if not you will see it with the dyno's WB, plus keep an eye on knock for the ignition side. Probably you are running rich. You can pull fuel out across the board using PIM volt, or do it in specific cells. I suggest you search around in the PFC forum. There have been a lot of posts regarding tuning and the PFC, and also larger injectors, etc.

Ray should be able to send you base maps through e-mail. I would just drive the 7 hours Ray's and get it tuned properly....safe then sorry..

Stevil

Ya, what can Ray do at his place? Just send him your PFC thru the mail. Unless SR motorsports has access to a dyno to tune your car(if thats the case, let me know).

you may know this already but there is a dyno at Area 51. i couldnt tell you what softwere they use, but i do know they have someone who tunes rotories, and its close by you. good luck

chris

artguy

I already called area 51. they cant do it.

xs holds a monopoly in the area....they dont have the time because of the move to huntington from fullerton.

I will call ray and see what I should do...Ill let you know as soon as I find out anything.

jason

ps..if any of you know someone local to the LA area with a wideband and datalogit...please pass me along...Id love to get my car tuned asap.

Hey Jason, Can't you pay one of the guys from XS on the side and go find a local dyno..? It would only take a couple hours...(You could do it after hours, before work, on a Sunday etc.) Just a thought.

artguy

I dont think I know anyone at xs other than eric (who worked at apexi and knows the pfc and its software intuitively)

Mr rx-7 tt

iTrader: (5)

You could try..? It would save you 14 hrs of driving and time...

Trout

Not trying to rub it in Artguy, but hopefully some others can learn from this.

Sounds like the moral of the story is don't buy a PFC or other complicated electronic part from a middle man who can't properly support the product. Yeah, the middle man saved you a couple of hundred bucks but now look at what it cost to make it right.

My bet is if XS sold the unit, they would find some time to tune it in their busy schedule.

The idea of paying someone from XS on the side sounds like the most feasible solution at this point unless Ray at SR has a dyno. RP is an approved PFC dealer with a dyno but Dallas is too far to drive.
Good luck,
Jack

Try giving Ralph at Excessive Motorsports in Hillsboro, OR a call, I know it's not exactly next door, but this man can tune PFC's in Rotaries, they have a dyno in their facility and Ralph himself has a FD with a PFC that is dynoing 600RWHP, here's the # (503)-693-2879.

artguy

thanks guys..

yeah..I know about the middleman thing...after waiting six weeks to get what I ordered I finally got it on and it didnt work out well....if I didnt have such a modified car it would have been easier...but it was a bit like dumping out a puzzle and trying to put some of it together in the dark. xs is the only place in town with a light to show me what pieces are what so I can put it back together.....and their light isnt plugged in at the moment...or its being used..I dunno.

however, I was trying to support the forums...and now wish Id have gone thru srmotorsports directly.

I will try excessive just for advice..possibly. thanks for the number.

I will call xs in the morning and try one more time....

thanks

Screw that, getting something the cheapest you can, instead of getting ripped off is the best way! Maybe XS can tune the PFC, but its a great product, with lots of us using it. You can get some help from us. Someone with a wideband and a datalogit, can do it just fine. **** you live out in Cali, how hard can it be? XS can go jump in a lake. For all the good things I here about them, they sure jerk people around a lot. They are not the only people that can tune these things!!! I'm sure if you got a datalogit, someone could send you a map that would be close enough for your needs.
The PFC is a great product, if you had a Haltech you would be having just as much fun, not to mention adding premix at every fill up.

artguy

if I knew someone with a datalogit and a wideband ....AND experience...Id be happy to go tuning...****..Id even do some artwork or something in exchange.

I dont think xs is jerking me around...they are just way too busy with other things....but I do wish there were other tuners locally that could tune the pfc.

I agree that it is an important lesson about buying something like that online...it is easier to walk in and deal with people in person. Id at least have gotten my pfc tuned as I specified...if it wasnt Id just go on in and deal with it...instead Im stuck with what I have and will find some solutions.

Ive been asking around...no answers as of yet.

Get ahold of Excessive, someone just made 461 hp to the wheels with them, check out the thread in the single turbo section about the T04S. Sounds like someone has the datalogit and they tuners knows what they are doing. If XS wasn't messing with you, they would have got you in. I can't understand the people that say, "just send your PFC to XS or Ray." and they will tune it for your mods. Thats BS!!! I've heard of tons of horror stories of XS and SR, maps not being tuned right. Too rich, too lean, not set up for sequential, etc... Why bother wasting $150.00 or more to have them guess??? Send it to me and I'll charge you $100.00 and tell you that its close enough and you won't blow up. You won't make any power, but you won't blow up either.

The only right way is to dyno tune the f*cking thing. You want, max power, reliabilty and to know what these things can do? Take them to the dyno.
Hasn't XS been moving for months???

artguy

thanks glassman...

excessive is sooooo far away. buy my girl would love the roadtrip...Ill put it on the list of things to check out. Id prefer to take the first solution possible. I want this car screaming by sevenstock.

I agree about having them guess tune it...it needs a dyno or a wideband.

thanks

Roadtrip!!!! Best of luck to you man, the sooner you get it done right, the better. I want to see numbers on these things.
Keep us updated, and use the force.
Good luck.

I think artguy was counting on XS to be up and running when he got his PFC - just like with with KDR - if they were down and moving (they have a few times) and I had all these mods and needed tuned I would be hard pressed to try and find somebody else with datalogit, a dyno, and experience with tuning rotaries. He's just caught in a bad situation. With that long mod list including the M2 twins and injectors it's tough to do all that tuning with the commander. If all else fails you might find a map like mr. rx7tt said on the PFC forum that's close to yours (even a modified single map) - just don't push the car incase you lean out. I know you want to push those M2s but sometimes waiting is best

artguy

Im going to have to become my own tech guy. lol.

thanks for the input guys...Ill let ya know.

artguy

just a quick update.

spoke with xs yesterday. Troy was very very patient with my concerns and has agreed to retune my vehicle as close as he possibly can until I can get it on the dyno in a few weeks. I am taking the ecu over to them today. Ill have it back by friday and will give it another go.

At least I get a break after all the frusterationg. Thankfully.


I spoke with sr yesterday as well. They wanted to just do a retune on the ecu...the dyno wait with them is four weeks. They wanted 300.00 to retune it. XS is who I purchased it thru the rx7 store...they have kindly agreed to help me eliminate the tuning problem that came with the untuned ecu at no cost. Muchos Gracias to xs for customer service after all the probs.

Hopefully it will be running better and I can get it on the dyno before sevenstock.
