No issues here. I think the cause of your limp mode could be trans temp. If they are the same as automatic Evoras, it’s not uncommon for them to have issues with heat.

Same no issues here and I track in Texas, so the ambient temps were 95F+.

When I come back to the pits, I'll open up the hatch and let the car idle for about 5mins before I shut it down. I've never experienced a limp mode from heat with this practice. Never had cooling issues on track either.

There are very easy ways to confirm your beliefs. That's all they are right now is your personal suspicions that you are pretending there is data to support.

The ECU did not "learn" your way into 15ph. The IAT and the MAF and the MAP are what they are. If you reduce restriction then you see the immediate change in the MAF. If you don't 'like' or 'trust' the charts provided by GRP who did testing for everyone, then grab another intake and do your own. The blue replacement filter is an easy option. It's possible that the GRP testing proved is that at 3,000 ft above sea level there is not much difference between filters. Or that the dyno he was using has a high level of variance that averages out to minimal differences between options. No one can really say. BUT what no one should be claiming is that there is some "magic" which invalidates his testing and dyno over your own results.

If I cared enough I technically have both GRP and Eventuri and i still have my stock one sitting around, I *could* do this testing, but I don't care. Critically though, I am also not the one claiming that Greg or his methods are wrong.

Even easier for you, would have been to prove that the Map0 (no JB4) to Map 1 or 2 was a meaningful change. Two different days running a dyno will result in different readings. It just is the facts.

It's nice to believe that you can regularly prove the incremental improvements you are making from a Day 0 dyno. But the fact is the conditions of that Day 0 dyno are never perfectly repeatable. So you could gain/lose 5hp just because it was a bit misty that morning. Just like with track times posted by magazine/reviewers, anyone with sufficient experience knows there are only generalizations. You cannot truly compare 2 lap times from two separate days and 2 separate conditions.

You regularly make claims that cannot be validated by anyone else, and speak loudly as if they must be true. When people ask you why you don't show the sort of 'rigor' your posts indicate that you care about, in order to validate these claims you offer weak excuses like "I know what stock is like I don't need to do a Map 0 run". Do you think its a coincidence so many people asked this simple question? Do you think everyone who did had no rational basis for the logic?

I think you are just wrong man and he is right.

Beyond that, he is trying to contribute while even though you say you have all the intakes “you dont care” enough to contribute.

Customer service from JUBU seems to be outstanding minus the language issues.

I was very interested in them until reading some factually documented cases where this is the exception. I do hope your experience goes well and you share the results. Could be awesome.

What's your deal man? I'm posting actual dyno charts and weights, you're just "pretending" you know better. Just because you seem to think YOU know better, doesn't mean you actually do. Either pay to get dyno results yourself and post them up, or give it a rest.

I don't think he's trying to be combative, he's asking for meaningful scientific rigor rather than reports on feel.

I think he's just frustrated because switching maps on the JB4 takes 30 seconds with the mobile app, and could have produced another really meaningful data point on your car with Map 0, Map 1, and Map 2 compared. People are hungry for additional full range comparisons of the map results on the same car, same day, same dyno.

 

[Tracked Emira]

No issues here. I think the cause of your limp mode could be trans temp. If they are the same as automatic Evoras, it’s not uncommon for them to have issues with heat.

Has any used any secondary transmission coolers that will help?

Then he should contribute himself... Eagle7 is not being paid to do this... he is spending money... is Tomwa his boss or something? I find this hilarious... I'm not trying to throw shade.. its genuinely funny at Eagle7's expense.

Guess I'll find out soon enough. And I will share unbiased experience with you guys.

 

[sbproducer]

My bad for hijacking the thread.. its gone off topic..

 

[ADC]

In the original spirit of the thread, I guess every one should probably... lighten up

ECU “learning” is the normal operation as they always adapt to changing conditions, such as oxygen density and different fuel. I don’t know anything about the Emira ECU but I find it unlikely that it would be different from my Impreza WRX that I drove and modded for 10 years.

Sure, but that's all about maintaining good driving characteristics. Part throttle response. Closed loop operation.

Open loop, ie wide open throttle, is "simplified" engine parameters.

Besides which, the Impreza you drove modded for 10 years. The JB4s installed on BMWs, Audi, Kia Stingers. The Evo I've driven for 5 years. None of these cars "backslide" and have their mods 'undone' by the factory ECU.

 

[benjh1028]

My basic understanding is the ECU learns to optimize the engine's performance based on the data it receives, but it doesn't have a memory of specific past events, modifications or behaviors. So, doesn't this mean that it essentially resets after every drive?

This is my personal project thread documenting what I'm doing with my car. It's not a Project Farm video. If someone doesn't like what I post, or how I document what I'm doing, feel free to start your own project thread and spend the thousands to mod and document what you're doing. I want to keep my thread free of drama so it's enjoyable for me, and for non-drama types who want to read it. Any future posts I deem unwanted, I will ask a mod to delete.

Back to adding lightness (thank you @ADC). Next week I have a few things I'm going to be doing.

After spending some time talking with SecondSkinAudio, and sending pictures of the wheel well liners for the Emira, they told me the exact product I need to dampen road noise from the tires. The liners are felt, so it requires a specific product. I ordered 2 sheets which should be enough for all 4 liners, and it's supposed to arrive on Wednesday.

The titanium 3rd cat delete pipe from Aerie is supposed to arrive on Thursday according to UPS.

When everything arrives, I'm going to put the car up on the Quickjack, and begin swapping the factory brakes for the RacingBrake CCB brakes I have, and as I do each wheel, I'll also remove the wheel well liners and put the sound dampening material on the backs of them.

It's going to be a bit difficult to judge the effects of the delete pipe, because changing to the CCB brakes will remove 23 lbs of unsprung rotating weight from the wheels. The bedding in process for the brakes is fairly intense, so it's going to be hard to tell how much different power delivery is with the delete pipe as I'm doing the bedding in process.

The delete pipe should relieve some back pressure on the exhaust, which should improve performance somewhat, I'm just not sure how much and I don't feel like spending another $154 for a dyno pull just for that alone (that's what each of these dyno pulls has cost me).

The guys at the dyno shop swear by flex fuel and E85 tunes, and I know there's one for the Emira and the JB4, but it's not quite as easy as just going to the gas station and filling up. What I think I might do is find out who the franchise owners are for the local Shell and Chevron stations, and see if I can convince one of them to convert one of their pumps to 93 octane. I'd much rather just do that than mess around with combining other solutions. There are 2 stations in the valley that have E85, but it's $3.88 a gallon which is only 19 cents cheaper than 91. Apparently E85 is a lot cheaper in other states, just not here because only 2 stations have it. It also would cost almost $500 to convert the Emira to flex fuel and get the E30 tune module.

SO.... that's on the program for next week at least.
