Acceleration issue - HPFP?

Thanks for that!

@Spencer@CorkSport; Do you have a link for gen one maps?

Wait...

stage 1 doesn't need a special map but stage 2 does, just because of the internals? How does that work? With more flow mods the pump is actually pushing more fuel than with less flow mods? Please get this one explained, I'm not following. The only reason I can think of for that is you're raising the demand pressure in which case you'll need to release a corksport relief valve very soon too.

I'm genuinely curious, I've run autotechs for 30,000 miles and have never had an issue with pressure or flow being off because of flow mods. I mean, you'll need to do a maf cal of course but that should take care of any issue that arises and is just standard tuning practice on these cars anyway.

I don't understand why all these brownies take the trouble of wasting $300+ on intake and test pipe but don't even bother to do fuel pump internals. Do they think that the fuel will just flow magically? It's like they are trying all they can to avoid it by saying "It was running fine until now".

Because VTEC.

Lol at the shit storm that this created. Stop being a shit head OP.

Let me see if I can get you any answer that is more technical than, "well it worked for me!"

Wouldn't basic logic say, more power and more boost = more fuel required. So a stage II map that is not from us would not take full advantage of our fuel amounts and either give too much possibly, or too little?

A stage I would not matter as much because even a stock pump should be able to keep up, and our pump won't be putting out less than that, and shouldn't be asked to give to much since it's just stage I.

I'm no COBB MAP expert though so maybe I'm backwards. That just seems simple to me, but let me see if I can find more info.

@Spencer@CorkSport; Is there a way I can navigate to this link through your web site? I'm only able to get there with this link directly.

So I chatted with my coworkers who understand this more and the answer is this:

The Maps were designed specifically to match our parts with the our pump. Now the Stage I Cobb OTS maps are roughly 5% off from what we have seen, so there would be no huge benefit to creating our own, unless we had a LOT of interest, but seeing as the majority of people upgrading their HPFP plan on going stage II anyway, they should be fine.

Likely, in the future, we will be releasing more maps, but probably not for awhile. It just isn't necessary.

We don't have a direct link from the site currently. We should soon.

Okay then. I understand that the maps match the parts, what part of the map is changed? MAF cal, HPFP tables, injector tables, AFRs?

@atvfreek; @rfinkle2; @ms3blackmica; @Lex; @RichieRichness; anyone done map comparisons COBB OTS to Corksport OTS? I'm genuinely curious about the differences here, I can't wrap my head around it and don't my my way around ATR well enough to figure this out quickly.

I think I can answer that. People who mod their cars seem to be split into different categories. There are probably several degrees of each group, but basically there are those with knowledge, and those with none.

I am one of those people with no knowledge. All my life (I am 42) I have always stayed away from wrenching on my cars. Never really had one worth doing it too. I had friends however, who were big into 1/4 mile racing. They all owned Shelby Chargers, or Shelby Lancers etc...They added mod after mod, and more often then not, returned from the strip on the back of a flatbed with holes in their blocks. They would then just rebuild it and go again. There was talk of chips, intakes, and straight pipes. I think everyone in this category is under the impression that these are the go fast parts that will make their car the king of the road. We don't understand, or have never learned, that these mods can affect anything else in our cars.

My first purchase was a SRI with TIP. Never thought about the consequences to a fuel pump. Didn't even know I had one. Then I started to read, and my world began to expand. I still know next to nothing, and still belong in the group of people with no knowledge. But thanks to this site, and to you guys who belong to the group of people who have knowledge, I am slowly beginning to understand how my car works.

tl:dr Because some of us are ignorant, while others are smart

Sorry anavrinIV.

I'm not of any help here.

The maps appear to be created using AccessTuner Pro which I cannot open.

My guess would be reduced HPFP targets to keep the actual HPFP pressure stable and prevent pressure creep.

Contact CorkSport to speak with the calibrator of the maps for more info.

[Gr33ntumb]

I'm glad my drunken ramble generated some cool discussion. The more info the better.

Awaiting the release to see results

Flash back to a stage 0 map and dont do any WOT's until you get fp internals.

Flash back to a stage 0 map and dont do any WOT's until you get fp internals. With the colder weather you will see more boost which requires more fuel. I was trying to run the JBR 3.5" intake and with the winter weather my fuel pressure was dropping into the 1500's so I flashed back to a stage 0 until i get my internals.
