Neither is anything else at this point. The dealership doesn't expect the new module to arrive until Thurs. So until then, our 6 month long project is just sitting at the dealership. I might be LOLing on the forum, but i'm crying inside.

On that note, I think everyone needs to cool out a bit when it comes to demanding update and getting upset when/if they don't come. Trust me, what HPF (and us) are doing is something that no one has successfully done before. So there are always going to be hurdles and roadblocks that are unforeseen. And sometimes it's reasonable for us to just keep quiet until we figure out the solution. And as we all should know by now, figuring out solutions rarely follows a schedule.

What happened to your CAS module? Car lock up on you, doesn't want to start to be tampered with?

Check valve sounds scary for everyday use.
We run a check valve on every HPF E46 M3 for the last 6 years. All it does is prevent oil from feeding to the turbo while the car isnt running.
The placement of the turbo is why this is needed, same reason why we need to run a scavenge pump.
Are you guys running an oil restrictor pre turbo?

I see your intention of showing us that you are supposedly anxious to get on the dyno soon. I'd assume this would be true, but at the same time, what assurance does anyone have that you will provide the same map to HPF for their single as you would your own? I realize that there are small differences between how the systems operate which will induce some differences, but when numbers come out, this is what people will speculate on. I'd like to see md5 hashes of the maps being used to know if we can compare 1:1 that, or the maps themselves in a password protected archive. In fact, you could and might as well post that part up right now for full transparency. Or to end this discussion, you have a single turbo map that you have customized and optimized all for your own where as hpf will be getting something a little bit different in terms of performance. At least there will be differences which could make the performance figures different that are map related.

This doesn't make any sense at all.

The implementations are different, so of course the maps will be different. What matters are AFRs, timing, boost, fuel params, etc., all of which play into making the most power with the biggest area under the curve. All those will be unique to each platform and car to optimize power.

doesn't matter what Shiv sends them...which i'm assuming is just the base single turbo map he has...because HPF is tuning it anyway to run optimally with their specific kit.

Come on, seriously? This is HPF...

They have software that can display and modify the fuel maps. Any moron could open up the editor and do a comparison. Besides, you'll be able to get both maps and hash the files yourself once they are released.

Also, Shiv is MAKING MONEY on every kit HPF sells...

I don't really understand the point of the post you just made, but it seems designed to start trouble.

Please don't turn this thread into a ****fest, I just want to see HPF progress.

Like they wouldn't realize if the tune had been messed with.

Yeah, guys... The tune HPF got was just a map to get the car started. Shiv provided them with nothing in terms of tuning aside from maybe a suggestion or two. What do you think the point of the Dyno is?

My assumption is that shiv is doing the tuning for HPF considering that the procede will be controlling it. Shiv may be 'making money' on every hpf kit but they are still in competition. All of those stats you mention are no doubt connected to these maps that shiv is providing. I don't think its unreasonable at all to suspect there may be a little bit of extra tweaking done on shivs initial numbers compared to hpf's to insinuate a hardware superiority.

EDIT: If all the 'tuning' on the procede maps in fact are being done entirely in HPF's camp then I suppose there is little debate. I just don't want shiv to come out and say my numbers were higher with essentially the same base tune and have no proof of it. Whats wrong with transparency?

Exactly, these base maps aren't likely to be released, why would they be? Without seeing them before tweaks are made then we'll never know. I'm simply stating this: If terry@bms started a single project and did the tuning for the vishnu single tweaked his maps slightly for power and stated he had a hardware superiority by saying the maps were the same we wouldn't be any wiser. This would give an artificial feeling of superior hardware design by showing better numbers. I'm not saying that they would do this, but a customers purchase will come down to this in the end. Which kit is engineered better. To say you won't be analyzing these numbers to see which one performs better would be a lie.

EDIT: Another example. lets say HPF puts out untuned numbers. If shiv put out high numbers, which he states follow the same base map but how would we really know if it was or wasn't truly the same base map? If the maps aren't released then we'd never really know it. Just sayin. Its just way too easy to say, my timing looks better because my hardware is more efficient and doesn't pull as much timing as XYZ kit does at redline.

Also, I'm speaking of these INITIAL numbers. In the end when tuning is done, the story will tell itself, I'm merely speaking of these first impression dyno figures. We're all wondering whose kit will perform better. I am.
