Waiting on your results...

 

The numbers don't look right to me and they don't look like the sheets you emailed to me either. Like I said before if you're unwilling to return the ECU there isn't anything I can do for you.

At present Brent is putting his car back to stock and I'll have another go at it with a series of different ECUs just to verify 100% that the same map is working properly on all the different ROM revisions. All the dyno testing I've seen so far has showed very consistent results.

Maybe your ECU isn't programmed correctly. I can't correct it if you're not willing to send it back. Sorry.

Because this is a totally different car, and the learning period was done for 2 weeks, not 1/2 an hour as the first one...

If I were to send it, I already know that Priority will take about a month for ~$20. If wanted it faster, I would have to choose Express shipping and that would be ~$50 to your address... I've already spent too much to keep on adding to that sum...

 

Cyanide, your ECU reflash story is cleverly documented but something doesn't make sense here. A stock replacement ECU with factory tune was messing you up (read previous post "ECU Swap on 4G69: '05 to '04"). Now you claim an aftermarket reflash is messing you up.

Reading the dyno charts post here does evoke empathy, but I am suspicious because no one else has complained about the hackish reflash which has been out for awhile and you seem to have a history of computer issues. And I am suspicious because of the refusal to send it back for examination - what more can they offer you than that? This isn't Sears taking back a wonky year old television with no questions asked.

 

If anyone is willing to loan a tactrix cable to my efforts that would be ok.
I would can flash my ecu with the stock map then flash it with the performance map. The shop in my area I can get 6 dyno pulls with a wide band. Not sure I would 6 dyno pulls, probably 4 max.

 

You're talking about this thread, right?

First of all, and saying it again, I did not test this on my RA.

When I wrote this, I had been with that ECU for about 4 days only. Nobody ever replied. Since I had no other option, I just kept on going with this ECU. I noticed a slight difference in AFR, but that was based on a narrowband O2 sensor, which is not accurate, so I didn't know anything until I got to the dyno in October after that (6 months later). The car was behaving perfectly, "better" you could say, so for the reflash, I bought another '04 4G69 ECU. This means that I was going to be swapping from one '04 to another, but again, I didn't test it on my car.

After doing that dyno, I compared it to the previous ones I had done before frying my factory ECU. The results gave about 1-2 hp more and a much leaner AFR, very close to the reflash's AFR, but the reflash AFR gave an almost straight line.

Now, you say many people have bought the reflash and nobody has complained, but also, none of those people have gone to the dyno. When I loaned it to my friend, he gave me the same reaction I read throughout the forums: "Feels awesome", "better throttle response", "feels quicker"... But, I always gave him the same answer: "until I see numbers, I will not be convinced".

Now, let me quote myself on this one:

If another buyer shows a dyno graph with different results than mine, then all I can think of is that my reflash was not properly done, but until this happens, I have to go with what I have.

 

It is possible the file did not write properly, that I have seen as well and all it took to fix the problem was for Hackish to flash it again and compare the 2 files.

Send the ecu back so he can compare the files...yes it will cost you but if the files are different I am sure Hackish will do the right thing, I am only saying this as I know the guy for who he is as a business man. I can see his stance, look I own an exhaust shop and guys try to pull fast ones all the time. I have also heard of a guy that sent in his ecu (BMW Owner no one from this site) for a flash and then said it did not work sent it back to Hackish and only when Hackish re-read the ecu discovered that it was not the same ecu that the customer sent in the first place, I am NOT saying you are that guy as I don't know you and you should and will be given the benefit of the doubt but from a business perspective you have to be on your guard I am sure you can agree.

Yes I believe in Hackish's work as I am a very happy customer with the worlds first turbo RA running on a tuned ecu (shamless plug) and I know the guy personally. Send the ecu back and I am sure he will take care of you as a good customer........

 

If I was trying to "pull a fast one", I wouldn't have gone through all the trouble of paying for dyno on 2 different RAs. I wouldn't have even complained about shipping it back and the time it takes. I wouldn't have waited months to post all the dyno tests I've ran, and I wouldn't be going public with this on a forum. I would've just shipped the ECU back and wait for my money with my fingers crossed...

There have been 4 RA owners interested in buying my reflashed ECU:
1st: Had a 2006 with JDM 05 front bumper. He didn't tell me it was an '06 until we installed the ECU and it didn't run. Hackish told me the '06 was CAN BUS so it wasn't going to work.
2nd: Friend of mine. Wanted to buy, with the condition that we dyno'ed his car before and after to compare, but his work hours were different than mine and he lived about an hour away from me. We never got the chance to coordinate properly.
3rd: The guy from the dyno graphs below. Do I need to explain why he didn't buy?
4th: Another friend. This one only minutes away and worked during daytime. He's the one from the first dyno graphs I posted. He was even more disappointed.

I asked for $400 from the first one, and $300 for the other 3... I still have my reflashed ECU laying on my desktop...

I even offered to mail the ECU back so that they could flash it back to stock, and even keep it for that matter (without asking for the extra $200 from the spare), since the results were nothing like it was published, and I had already sold the car, but this was when no more emails were answered.

Just in case, here are the first dyno graphs of the first attempt on running the reflash on a dyno: Blue=reflash Red=stock



Mods on this car:
- CAI
- UDP
- Factory header, no cat, factory muffler

Conditions on testing:
- 93 Octane fuel
- 1/2 an hour learning process
- 5pm, dry weather

The results were totally different. In this case, there was no hp or torque loss, but there was no gain either. That's when hackish explained that I didn't give it enough learning time, and that is why I got another car and loaned the ECU for 2 weeks to ensure that a proper learning was done.

As of now, I'm waiting on Ralliartize It to dyno his reflash and compare. I don't know what brand of dyno he'll use, so I don't believe max values will be the same. As for changes between ECUs, he's asking for a donor on a spare factory ECU, so all he has to compare it with is my information, unless he can get another RA to that same dyno on the same day he goes. If he doesn't do DynoJet, then values could be way off, but if he did, I could send him my DynoJet files (or he could send me his) and we could do a graph to graph comparison.

P.D.: I'm not mad at your comment of "pulling a fast one"... I'm just explaining myself...

 

The place I will be using has a Dyno Jet

 

Cool. Let me know when you get your results.

 

I did not say you were trying to pull a fast one I said as a business owner I have to be aware of that. Sorry if it came across that way I didn't want to insult you or insinuate anything toward you personally.

Having said that I called my buddy that had his car done, he has since sold it but still has the dyno sheets I will post them when I get it. It clearly shows the power difference. I see your results and I believe that they are honest results. Based on that information something must have went wrong with the flash, I am not a tech by any means but something is not right and does needs to be analyzed and fixed.

 

Thanks, and don't worry. I edited the post later on to say I wasn't mad about that comment.

Anyways, let's see how it goes with Ralliartize it's graphs. At this moment, I'm a bit pissed off at the results, but I guess I have no option other than to ship it back and go through the whole learning and dyno process again. My friend is in stand by for me to do this, so I'll wait for Ralliartize it.

I'll have to go with Express Mail if I don't want to wait another month on this, and I have to pray that my friend doesn't break his RA in the meantime because he likes to race... A LOT...

Waiting on you, Ralliartize it...

 

Me toooooooo

 

Although I'm pissed at my results, I wouldn't do this. You would be changing maps, and proving me right (or wrong) won't do you or me any good. I believe Hackish will know if you tampered with the ECU, so if you go through with this, you can say goodbye to any future upgrade, update or service on your reflashed ECU.

I believe your best option would be to find another RA. You could run yours against it, but this would mean that they'd have to be identical in mods and condition. Or, you could could just take the other RA's ECU and do some dyno runs with it. You would need to run it at least for a week before you could dyno it again to allow the learning process for the stock ECU since you have been in your reflash for a couple of months now.

IMO, don't mess around with your already reflashed ECU. Just run some tests on it and compare.

I'm waiting on your dyno graphs, but I'll be sending mine back to Hackish by the end of this week. I'll be spending some more $$, but I have to get to the bottom of this.

 

The reason behind the tactrix cable was that I would flash my ECU would stock map then Hackish would send me the reflash map and I would flash the ecu back with that. I've already spoken to Hackish in regards to this, no guarantee this happens though.
