I'm supposed to listen to some 2 bit tuner that had to pretty much steal a tune under the guise of giving advice to somebody? I've read your stuff and at the least unimpressed.
I hate to hear a good civil discussion get bombed with attitude. In my opinion if you have a personality disorder with someone take it off the boards. I have the utmost respect for Decipha and the knowledge he shares.
As far as my opinion and experience with PNP ECU's as an end user and not a professional is posted in this link. https://forums.corral.net/forums/engi...ly-driver.html
For the sake of not rewriting it, here it is the copy and pasted.
This is another great discussion here, and maybe an opportunity to think about how we, the novice tuner thinks about tuning or lets say getting your modified engine to run well. Most people here who are asking the question as to which PNP system is best, are looking for a system that plugs into the stock harness and with support from the designer of the ECU through tech forums and tuning manuals to get there car running.
Inputs and controls are something for sure to be considered, however the biggest task on hand is to learn how the software works with the ECU and apply that to get a engine that runs well under all conditions, like an OEM tuned motor. I think this is what we all strive for with a tuning system and where we meet the biggest challenges as well.
Now back to the term PNP. The only system out there that I know of that can claim it's a true PNP is the PRO-M system. Michael Plummer and others on the Corral have proven that, but to the moment Michael is the best example and has it well documented. Other ECU makers claim PNP, but in reality it means something to the effect that you can plug it in to the stock harness and works with OEM sensors but no doubt a steep learning curve is hidden in all of PNP promised by the ECU makers. I really see this as a fundamental issue of changing ones attitude and understanding and experiences with what's on the market for aftermarket ECU and tuning software. To Include myself in this understanding, it's almost like changing your religion, and not easy to do. I have talked with Michael many times and Chris at PRO M trying to understand and fashion the idea that a system that properly calculates load via a properly calculated MAF with an ECU designed around it could truly be PNP, "PLUG AND PLAY" and emphasis be on the play! Could it really be that simple, it's was hard for me to believe, and I imagine many others doubt this as well. I think the proof is in the pudding in Michael Plummers case.
I built my own car and it's motor and designed a unique system and have strived to tune it via so called PNP systems know for over 8 years. I started with the piggyback Anderson Ford PMS, then had help tuning via SCT chip through mail order tune, then 2 years with the A9L EEC and Quarter Horse, and now with a Megasquirts based system. With all of these systems there was a learning curve and support forums to help you along your way, and good help can be hard to find out there, as many people just claim they know what there doing and add to the confusion. Usually the Tech people are very good, but is it truly PNP if tech forums are needed with endless threads with people looking for answers sometimes never solved? I know I have spent countless hours with techs creating threads driving with my laptop, idling in the driveway, driving my neighbours crazy tuning cold starts and idle transitions.
My point to the OP is this, with all the other systems out there you will spend a lot of time trying to figure out why your car won't run well until you start to learn the complexity of the system and tuning. In capable hands, meaning an experienced tuner, I'm sure this can be accomplished sooner, but is that why most of us by a PNP system?
My hats off to the people at PRO-M for offering a breath of fresh air with a true PNP system. I've been on the cliff many times in the past years tuning with other systems, and not for lack of trying have not achieved the drivability and reliability offered by the PRO-M ECU. I have finally thrown in the towel and will be going to the PRO-M system and am currently waiting for my kit. I will be following up here and on other forums with my new PNP experience.
