RRM ECU - Small Issues
Amax, I don't think anyone is saying the PB sucks, or that no gains are to be had. I think what people are getting at, is that this device is advertised to work out of the box and be 100 percent safe. The values that quite a few people running the PB are seeing are simply NOT safe. With a tune, problem solved, easy as that. I'd also consider not stating your cars values are completely safe and you're running great without dyno'ing your own car. People who are having problems are qualifying their statements with a dyno, and a legitmate concern. They have a right to be concerned, they may have been misled. It's great that perhaps you and your associates were not, I think that everyone's just suggesting to ensure the safety and longevity of your car, spend the damn 20-30 bucks to put it on a dyno and make sure.

I know PRMivec, I was just trying to get a laugh. You'll be glad to know I set a dyno tuning apointment for tuesday. It's on an older dynojet that reads low but no matter, the guy is supposed to be good. Will definitely post my results.

Have to clear things here too. No one said the PB sux, it doesnt. All I wanted to say with the thread i made was that there might've been some problems with some of the maps and that i recommend you guys to go visit a dyno and check the A/F mix. There are more than enough ppl that saw my leaned map and ive got no need to continue this debate. If the car feels good on your ***, then by all means keep driving it. These forums are here to help fellow ralliart owners and i felt my info was useful , but i guess its better to call it rumors than to loose some sales.

please by all means... have them put the wide ban in so you get a afr reading....
Just got back from the Dyno an hour ago. Interresting results. I'll try to scan the actual sheet in later. First of all it took the tuner a while to figure out the software so by the time he was actually tuning we didn't have much time. In his opinion, was the car running too lean? yes. However, the AFR readings were only in the 13.8 range max which he said is too lean at WOT. He tuned it in the 12 to 12.8 range I believe.
Now on to the results. After tuning, peak hp increased by 3hp to 160 and peak torque increased 11ft/lbs to 162. However, the big difference came between 2700 and 4800 RPM (yes most of the useable power band). To pull a couple of points> At 2900 rpm gain of 13hp, 21 ft/lb torque. At 3650rpm gain of 14hp, 17ft/lb torque. At 4450rpm gain of 19hp and 22ft/lb of torque. This was definitely worth the trip!
The tuner said he could keep going but it wouldn't change much. He was happy with the new AFR curve. He recommended a less restrictive exhaust before more tuning.
Now for my opinion on the RRM Piggyback ECU. Is this a wothwhile product? Absolutely. It is perfect for tuning your car for different mods. In fact, I would say a must if you're getting into headers for example as this will definitely cause your car to run lean. Is the stock piggyback map 'plug n' play' as they say? No. For Injen Intake and RRM pulley, it is too lean and not optimized for power and torque. Just my (and Mike the tuner's) opinion.

Have you splice the wires or just cut them ???

Idle wasn't any different or rough, just perfect... CEL light is on but I guess the ECU will relearn and it will go off
I have to drive for 15-30 minutes... I'll go and drive it softly... see you !

thx for checking that up and congrats on the gains
Just wanted everyone to know the piggyback was up and running fine again.
I also noticed while checking out the SRI the seal on the O-ring busted, that could have been ****ing with the sensors.

Mine working fine as well, maybe since I still have my OEM exhaust I ll have to get it dyno tune... the car hesitate a little around 2000 RPM but the engine feel stronger at 3600 RPM to redline
don't know if I gonna bring it this year to dyno.... because the car go in the garage 15th of november..... to 15th of april......... DAMNNNNN
