i just sent a pm to rock about this issue and he said its been jsut a rumor going around that the pb is lean and the map is safe and no detonation will occur from leaning out..

hey rezonate did you get your issue fixed??

 

I'm supposed to send it back....he thought it was due to the installation even though its rock solid. Something is wrong with the map or the unit.

 

You can believe that, but other people's experience has been otherwise, like here:

Again, I'm not trying to badmouth the PB. People have seen some very nice gains. Some even without tuning. You are taking great steps to ensure the safety of your car by heading to the dyno if you install such a part. If there's no harm in the tune you are running, hey it cost you $20-$30 bucks to find out what your car puts down and give you a little piece of mind. I think its completely reasonable to think that there is a possibility that environmental conditions, and different mods might require you to run a custom map - and it never hurts to be prudent. Chances are, if you're like me and needed to ask Rock in the first place, you may not know enough to trust that you can do it yourself properly, but you're concerned enough to think you may just blow up your gear.

 

RUMOR??? Im not one to vendor bash but I can easily post a video or pics of my car throwing a 17+ A/F mixture. Its easier to call it a rumor rather than say it was one huge *** mistake I guess.

 

The PB is a mod that most people just put on thier car and thats the end. If more people were to dyno i'm sure we would have more of the same. Eventually I will re-install my PB and put it on the dyno(or at least check the AFR.

 

Rumor?
of course from rock's pov is a rumor he has to wash his hands somehow...

i saw the run, i saw the graph, and i saw the map IT WAS DONE WRONG from the beggining... so dont try to convince me it is as safe and in no need of tunning out of the box with some minor mods when is not true...

 

that is why i do not trust the comments that say it is an awsome mod and i feel the power because is not true... you see comments like this:


"I finally got this installed, and I have to say, so far, im pretty impressed with it. The first thing you will realize without a doubt is how much quicker it revs up to 3 thousand RPM's. Where you really start to feel the power is 3500 rpm's and above, then the thing flies like a big *** bird. The power is no kick in the a$$ acceleration, but its the first mod that I actually felt SOMETHING from."

that is a placebo experience he 'felt something' WHAT?

as i have said before GO TO THE DAMM DYNO the power gain is not measured by the extent of how much your *** dives into the seat and how much noise the engime makes...

 

Well, a dyno for me isn't possible unless I drive two hours. I think after they look at it I'll see what the issue is. It could be running rich also, the car has been noticably slower in the range that the car now hesitates in. I want to stop assuming things though until I find out what is actually wrong.

 

just to let people know - I have the PB ECU and it and my car are running smooth. Sorry PR-Mivec, but there IS definitely a power improvement. It's actually easy to feel - not just wishful thinking. Have I dynoed it? - no, but several people have. There are a couple of Ralliarts on the Dyno listing with just intake, PB and maybe pulley. There's a 164 WHP and a 163 Tque. These were stock maps. Some guy here recently ran on a mustang dyno at 155 HP which is very good (likely around 167 on a dynojet) and he also saw that it had no unsafe values. That said, I will probably have it tuned as well and will certainly post up resultswhen the time comes.

 

have i said anything about a car not running smooth? no i havent....

is it wishful thinking? YES untill you confirm an actual gain and know if you car is running safe... if it is then you are ok and good for you

deathsythe's car before and after the dyno ran smooth BUT TOO LEAN (AFR 19) that is my only observation... so until you actually confim your status on the pb dont try to justify it. is it wishful thinking to go blind-tunning a car, dumping money and time for what 164hp how pathetic is that? (aprox since you havent dynoed) who is doing the wishful thinking you or me?

i have work on and tune a lot of ra's some came with the piggy all were lean, they all dumped the piggy and all became normal, is this a logical problem no.. is reality
talk to me with numbers not a fantasy of how it feels behind the seat, that is all i ask.
dont show me graph of the brand show me the graphs of particulars... this is all i ask

 

No, you didn't say anything about the car not running smooth, the guy whose thread this is did!
Looking back through some of these threads, I believe DangerousDan took his car to the dyno, and the lowest value was 8.9. It is my understanding that this is not a dangerous A/F ratio value. So, it is obvious that there was a problem with SOME of the units but obviously not all are running lean. By the way, if you tune a lot of ralliarts, why would you dump all the piggybacks instead of tuning them? Look at the mid-range gains deathsy? got by tuning it. Were these cars getting CEL's with 'running too lean code'?
It's not a fantasy that my car runs better with the PB, it does. It was bogging down slightly in the mid range after I put on CAI, now it pulls hard and smooth through that range. Period. How your car drives is as important as dyno numbers. I do, however believe all piggybacks should be tuned ideally and will hopefully do mine soon. If I do and there is no lean condition though, you owe me $150 .
Yours Truly,

Another "Pathetic 162HP Ralliart owner.

 

see you do not know what you are saying... the 'lower value' is in regards to the program not the afr... you need to know before you try to argue

the reason i do not kept my piggy is that i went, for a full custom ecu made here the reason the piggys got dumped was by desition of the owners of the cars, not mine... because, when you do not see results as advertised out of the box, no matter what method of convincing customers will get pissed off at me as tunner and at the brand of ripping them out of the money.... see the difference..?
have I tunned piggys? Yes, after some dyno hours up to 45 hp after mods with an afr of 13.1
so keep being on the crowd of butt dynos ill bet you will bend the seat someday...

 

i was one of those he helped and i decided to re sell the ecu because at the time the software was not out for sale.. no matter what people say now i will always think that was a waste of time...

 

I'm with PR_Mivec... this is just like when windows 98 came out lol 2 buggy.

 

Actually, I do know what the values represent. They are merely plotted voltage points to given RPM ranges with 10 being the mid or zero point and 20 being the max positive voltage shift (2.5) and 0 being the min voltage value (-2.5). These plotted values are what in the end determine your AFR changes.
All that last comment tells me is that you think I'm fat. Remember, not everyone has cheap access to dynos as you seem to.
