VSA, ABS, anb SH-awd.. i have some debris in the wheel sensor hole as i had to drill out the old one and i guess i did not get it all.. i need to take the axel out and clean the pickup off... Here is a 60-100 roll.. ya i smoke bad habbit but stressful life hahahah I cranked the boost up in the 2,3,4th cels to 2.200 just to give you a idea hahah i need to turn it up on the top end now. I just sent vit 6 logs and feedback.,.. 2 pulls on standboost with the vsa box off and then on and 2 high boost pulls on and off.. i gave him a ton of data!!

So do you just need to download the latest beta version of Flashpro software and adjust the calibration with that to take care of this boost issue?

bluecarbonfiber

hondata hasnt updated there beta yet we will need to wait for it before we know its added and fixed

rdxchris710

Sorry guys got the word back from vit.. No go. The check box does nothing. He sent the data to hondata and they are going to continue to look and I'll have a update when they find something. I did adjust my top and boost . I have. Soild 15 psi all the way to 5k. Soon the timing issue and the 16.5psi boost cut are the 2 issues hondata is working on. I've found just rolling into the throttle is better than flooring it, with the boost adjustment the car is still insanely quick..I cooked a FRS / brz last night.. Wasn't even a race.

I hope so, those are 15sec cars (FRS/BRZ)...

hypnotini

ive done the same test as rdxchrist but with a bit different results so we shall see.

Nachtsturm

I thought the same exact thing.

An 89 SHO would give one of those a run for its money.

KenB350z

Lol. Oh man. I remember those things back in the day. The SHO 32v V6!!!

yeah ford had Yamaha design that motor.

Nachtsturm

They were awesome. Had 4 SHO's over the years. 89, 91 Plus, 96, and a 99.

This was my 89. Had 59K on it when I bought it. Feels like forever ago.

That they did.
My 89 V6

My 96 V8 (Oh did it sound mean)


These pictures were taken with a Mavica lol.

rdxchris710

what are your boost settings? The lag between 2-4 gets worse and worse as you raise the boost... it makes a soild 17psi but does not go anywhere. I must say on vits tune.. ive been able to jack the boost up farr and still 0 knock. Once and a while i get 1 count on cylinder #3.. its alllways #3 anyone have a explination why only 3 would pick up knock? As of now its more of a highway ripper..5-3 downshifts are insanly fun and addicting. Ill make a video today showing how bad mine is between 2-4k .

KenB350z

Yeah mean! These times would be a nice goal for the RDX...

Yo Chris


I have my boost set at 2.050 up to 5500 and then 2.000 up to the last one which is 1.950 I'm getting exactly the same thing as you: occasionally 1 or 2 knock counts on a 10 minute datalog on cylinder 3. I'm holding a bit lower PSI - about 16 ish tapering off to 12 (I'm very happy with it, because I can set the overboost limiter back to the factory setting. I'm getting almost the same readings as you. I asked Vit about it, he said it was just noise. Real knock would be a sudden spurt of a number of counts and you'd be able to hear it while driving.

hypnotini

my rdx is bi polar. it knocks it retards it like boost it hates boost depends on the day.

rdxchris710

I've got a lot of work to do on the my boost curve. I have it holding a soild 14-15 psi all the way to 6900.. The bottom end sucks and I can hit boot cut going wot in 4th say just crusing. I'm gonna take my buddy out today and really dial in 4000 and below boost targets. I felt it do a major retard and man you can tell. I need a retune for my dp but, I have other things that I need first.

csargemg

Whoof that's pretty impressive. Yeah, I wonder if I could smooth out my bottom end I'm seeing that dip, though mine is most noticeable about 3000-3600.

more testing going on... new turbo feels good though. more to share after I get all the numbers together. gaskets, shop cost, and of course HP & TQ but that only happens after the tuning bugs are worked out.

your doing great things keep trying to educate yourself and I hope that based off of all the data we (the community) give hondata and VIT VIPER that they will be able to give us a better 10/10ths tuning solution!!!

csargemg

I'm playing around with cylinder trim and knock retard now, a little bit. It looks like if the ECU registers a knock event, it will pull timing in a similar spot. I'm trimming the cylinders to balance the count (on a 25 minute datalog with a couple pulls, it's at 3 on 3rd, 1 on 1st, and 1 on 4th). That's pretty close. Pulling all cylinders half a degree and see if I can get a log with 0 counts, and see if that IGN pull back still happens then.

Happy to post logs and cals if anyone is curious.

The problem has been found. It is torque reduction before the factory boost limit. It's complicated with IAT, air pressure, rpm, boost & retard tables, but the ECU was retarding timing to make the boost cut less severe.

We will do a release tomorrow. Thanks for your datalogs & testing.
Hondata


its fixed guys! hondata will be updating tommarow.. hold onto your pants!

rdxchris710

Its fixed, update your fpmanager to 2.1.3. Its so much more enjoyable now punching it and having it actually "go" under 4k is awesome.

Tomtwtwtw

So I'm a little confused on the fix - did they unlock the tables needed to fix this issue or was it something in the FP Manager software itself that was corrected? I guess in other words, do you have to adjust anything on the tune after you download 2.1.3 or reload and reflash the current tune?

GSJake

Thanks for your and the others who helped iron this out Chris!
Like Tom has asked. What needs to be done for this? Is just the FP software itself updated or is it both the software and preloaded maps that have been updated?
Thanks again!

csargemg

Here is what has been released:


VSA torque limiting enabled checkbox.
Factory boost cut retard enabled
Factory boost cut enabled


This allows you to turn off the factory boost cut ignition retard, which had been why timing retarded as boost climbed.


Sure, this was a protective measure. But it was designed to keep a hundred thousand engines, all running oil through the turbos, with the same tune, reliable through warranty (originally 6 years/60k miles) safe. If you're getting yours tuned, checking for knock, and realize that you're beating more roughly on your transmission, you'll be fine! But that's what it means to be an enthusiast, after all.


In short: With this update, it really feels like Flashpro has been unleashed.

csargemg

These are not weak trannies, fortunately. Just had my ATF fluid checked at the Acura dealer - got a free multipoint inspection and they were rather impressed by the mods. So unless you're doing something wild and crazy (I'm looking at your big turbo, Wrench) these transmissions can take a lot of abuse.

Tomtwtwtw

Awesome, thanks! Does this help eliminate that dead spot off the line? I understand the characteristics of a turbo engine, but with how responsive this is while moving, the size of the engine vs. turbo, and how the power kicks in...always felt like there is something else holding this car back in first gear.

TheWrench116

iTrader: (1)

yeah if you get retuned it should make the traction control light blink at you from a dead stop. mine does with the T20 but its not done with regard to tuning yet.

rdxchris710

Dead spot is gone for sure. With my boost numbers I hold soild 15psi right to the limiter.. Took me a little while tweeking it here and there but its a straight beast.

Tomtwtwtw

Ahh...I've been slacking on getting my latest revision loaded, but I'll make that a priority tonight and log it so Vit can hook me up on the next one. Thanks for the input guys!

TheWrench116

iTrader: (1)

are you doing tuning with vit now?

Tomtwtwtw

I am, yes.

GSJake

Looks like there are a lot of people on here getting tuned by Vit. I assume he is aware of the latest developments pertaining to the RDX in the FP software?
Its summer now so I rocking the Lex but come fall I will either take it to King Motorsports or Vit. Keep us posted.

rdxchris710

I'm waiting for my newest revision. Been a day or 2 since I sent logs. Vit is aware of the updates in FP he was a major part in helping us get it unlocked.

RDX10

Hello,

I just have a few questions for some clarification:

1 In order to have your RDX VIT tuned, you need to purchase a flash pro correct?

2 You order the flash pro and then you purchase the $230 package from VIT's page and they will send you all the steps to send them a log of your car's performance correct?

3 You do not need any add ons for these tunes correct?

4 I have to do nothing on my part except load their files onto my ECU and then send them performance graphs...etc other info, and they will keep on altering certain things and sending me new files until it is all good, is that correct?

Thank you for the help

TheWrench116

iTrader: (1)

more or less yes that's correct.

RDX10

Great! Thank you!

I may have missed it, but what is the most power someone got out of VIT's tune?

TheWrench116

iTrader: (1)

there should be an answer to that this afternoon one of the guys has a dyno appointment.

RDX10

Thanks for the reply! I guess the dyno didn't pan out today.

Tomtwtwtw

While I'm also curious about the answer to your question, its relevancy is not high unless you are running the same mods as the person that got the tune. The are a couple guys getting ready to go big turbo, and of course they will make big turbo power regardless of who tunes it. Even more important than the power figure though, is how the power is made. The good tuners will pay close attention to knock, fuel trim fluctuations, etc to make sure the tune is safe, even if it means giving up a few ponies. It's easy to make power, but it's also easy to blow up an engine if you aren't paying attention.

RDX10

Good point!

The only reason I ask is because I don't feel that Hondata provides enough of an advantage, though I am sure it is noticeable, it just isn't the kind of gains I am used to seeing from other tuners. For example, the Tiguan 2.0t engine makes 200hp/209tq stock, but a stage 1 tune yields anywhere between 60-90hp bump and 80-90tq bump without any other external hardware.

So where am I going with this? I was hoping that VIT tunes would be able to provide a decent increase in hp/tq just like the tunes of other engines without the need for extra hardware. I realize that longevity is just as important, however I know many people who have tuned their VW 2.0t engines upto stage 3 and have been running problem free for years, so I don't understand why we don't have a more aggressive tune.

I think I remember reading something about timing or the type of turbo or some other hardware based issue that is preventing us from getting a better tune, but I could be wrong.

I will give full disclosure so that I do not get flamed, I am not very familiar or well learned when it comes to turbos, I have never had a turbo vehicle before and yes I may be overlooking something major here so please go easy on me if I have.
