I have a mild street port,fmic,downpipe,midpipe,catback,hks intake,uprated pump and fpr.I need to know how safe or unsafe this set up is as i cant find anywhere in the UK who can map it properly.Thanks for any help.

 

I would say not very safe, IMO. The stock map of the PFC is leaner than the stock ECU. I would suggest keeping your boost at stock levels until you can get it tuned or locate maps for mods similiar to yours.

 

That's weird.

I just talked to Ralph at Xcessive Motorsports...and he said the PFC's stock map for the 13B-REW is MUCH richer than the stock ECU.

 

no ways, you really need to get it tuned.

 

Since when? Out of all the threads I've read and the people I know reading their o2 voltage and even taking their FD to a Dyno with a wide band, the PFC map consistantly came up SUPER richer than stock. Did Apexi recently change the maps?

I know mine still runs super rich. I got full exhaust, efini y-pipe and at 13.5lbs (with new o2 sensor) I still get o2 voltages in the lower .90s and high .80s.

 

Some people have said that the PFC base map is leaner than the stock ECU. However, it could be just the timing has been adjusted. People do notice a performance difference when adding the PFC and using the base map, there isn't a lot to play with other than A/F and timing.

I would still say that running an untuned ECU is still playing with fire. IMO, if you are going to get a programmable ECU, get it tuned. I can't count the number of threads with people blowing seals on untuned PFC's especially if the guy experiences any boost creep with his setup.

 

You need to tune. That is the only way to run safely. Also, you will pull extra power out with proper tuning

 

flybye, do you have version 5.08?

 

Oh of course, but most will agree that you should only go so far with the base maps until you need tuning. I was going to get mine dyno tuned with KD Rotary (when I lived in Jerzey), but Jeff told me not to even bother until I get a larger IC.

I've never gotten any boost creep. My boost is solid all the way through.

I DO know people that just sell their "Tuned" PFC to someone, and then the buyer mysteriously pops his engine. Like we always say, every engine is different

 

As soon as I get home, I'll look.

 

If you look at the results of Wade's dyno testing, the PFC map is leaner than the stock ecu. This is normally OK as the stock ecu map is pig rich.

Dammit..

This f'ing forum has so much conflicting information I'm starting to get kinda ticked off having to wade through it.

Who the hell should I believe? A guy that dyno-tunes 7's all the f'ing time..or another guy that's done his own dyno-tuning.

 

Believe the guy who tunes RX7's all the time, Ralph knows his ****.

 

ARCHANGELX
take everything on this forum with a grain of salt

 

Yepz...I've got a whole box of Morton's right here.

I can't wait to get my car dyno-tuned. HURRY UP AND GET THAT DYNO UP, RALPH!!!

 

i rarely listen to what people say on this forum, especially when it comes to the big risk of detonation.

After spending almost one year here i've gotten scvared of how the talk goes about how fragile the 13B REW is.

I think some is that i dont want it to blowup so i don't listen cause of that, but also i've gotten the feeling that many people in usa don't tune or just don't know what they're doing.
I don't know anyone where i come from that would try tuning themselves unless they have much experience. But in usa i've heard many people who do it themselves.

Caution!! Don't take this personally if you're from usa Caution!!

 

Hehe gotta love the europeans! So honest and direct, yet so respectful.

 

that was just my 2 SEK

 

I know with all the mods I had the Base Map was actually too Rich for me. By a lot....and I have an FJO wideband so I'm not guestimating.

You still need to tune. I would use someone's maps that are really close in mods to you, but with conservative boost until you can get a WB.

my 2 cents
