yeah just gotta be carefull who your sharing with maybe more region specific for example im at a mile high and only have acess to 91 octane without going to the expensive specialty fuel place so that particular tune could run a lot different up here in Colorado.


also with the next flashpro update they are unlocking the boost cut issues so things are gonna get buck nuts round here.

good point ill remember that in the disclaimer. I think at those altitudes it would be rich.? I think??? and I might be changing my combination again soon anyway. maybe fuel pump and head studs first but hopefully soon.

You guys really should stop watching the knock sensor so much. I don't even run one my built cammed k24. Oems are sensitive. Turn it off if flashpro allows it.

TheWrench116

iTrader: (1)

is the car boosted? and did you tune it your self? I like the safety factor that it provides.

Slow98teg

No boost. its aftermarket piston/rod/valvetrain/single lobe cams. I don't tune myself. There are so many things the oem knock sensor can pick up. I mean its good to keep an eye but I wouldn't base your whole tune off it. Just my .02

Has your dyno been awd or pulled driveshaft?

TheWrench116

iTrader: (1)

Pulled the drive shaft. All pulls in 4th gear. No water meth. And I got 335 miles and it took 16.476 gallons so I'm looking at 20 MPG in mixed driving.

bluecarbonfiber

have you noticed since you tuned your vehicle if it ever backfires? ive noticed with mine it backfires everynow and then.. usually when its cold and i gun it a few times.. now sure why this is happening my guess im still too rich.. i wanted to add the 800cc injectors soon but was curious if your having that problem as well with your tune

TheWrench116

iTrader: (1)

no back fires with mine that I know of however my diverter valve makes a popping noise once in a while. part throttle cold condition maybe the same thing.?.?.

bluecarbonfiber

for me it sounds like a loud popping sound i cant tell if its louder through the intake or the exhaust haha its kind off a mixture if that makes sense it reminds me of a backfire only is felt through out the whole engine area

TheWrench116

iTrader: (1)

so if you want your particular combination tuned and are willing to travel I have pricing on dyno time and the shop number to call to schedule your session. if you don't have injectors I cant help you. I'm not going to waist your time or mine. PM for details.

bluecarbonfiber

any issues with the new update and the overboost showing up?

Tomtwtwtw

Question on your tune - I was looking over the parameters in the stock tune a while back and I noticed that the ECU appears to start pulling timing very early on in relation to IAT temps - way more aggressive in this regard than my previous car (also turbo-charged, with smaller displacement and more boost). I feel it in my every day driving as well, especially during the warmer days after I have been driving for a while. Did you adjust those tables at all?

TheWrench116

iTrader: (1)

I have mine set to a safe margin so as not to have any safety concerns with the motor. I would rather be down a few horsepower then have to worry about blowing up a motor. I've it set to start pulling timing and adding fuel. which will cool the combustion chamber and reduce power as well as the potential for damage.

TheWrench116

iTrader: (1)

going to be going back for a retune soon as I've decided to up boost pressure now that it actually will hold the set pressure now. I'll post more when it gets closer.

bluecarbonfiber

imagine what you could do with an upgraded turbine =)

TheWrench116

iTrader: (1)

you mean turbo? or compressor right?

bluecarbonfiber

compressor wheel.. some people call it the turbine wheel.. Soda vs pop =)

TheWrench116

iTrader: (1)

compressor = intake, also see cold side
turbine = exhaust, also see hot side

bluecarbonfiber

interesting.. ive always heard it refered to as both.. must be a oregon thing we like to keep it wierd =)

TheWrench116

iTrader: (1)

this is the correct terminology. further more if you look at kens rebuilt / modified turbo you will see that he had a compressor wheel replaced with a larger one capable of more air flow. he had his turbine wheel clipped for more flow on the top end at the sacrifice of some response down low. compressor wheels can be swapped the turbine wheel is not change able as its part of the shaft.

Tomtwtwtw

Ken went about as big as you can go for the stock housing, right?

TheWrench116

iTrader: (1)

he had the first one. as far as the biggest you can go ??? depends on who you talk to. and who has actually seen the turbo and had a chance to take them apart.

TheWrench116

iTrader: (1)

still cant believe no one wanted to get a good tune and on the cheap either. well now its back to the drawing board. I'm setting my tune date in January and if you can make it that day great if not your S.O.L.
thems the brakes.

KenB350z

That is right, as big as you can go safely with reliability; yes.

crxtype-r

wrench i'll join you, my exhuast should be done by then .and i'll hit u up later to confirm . sending the turbo to blouch in lebanon pa. next week . doing full port ,seals clipped turbine and 19t comp wheel and new bearings / cartridge. whole overhual with port match on the exhaust manifold don't know if it will be back by then.but i'm in !!

KenB350z

Well from looking at it apart, it doesn't look like you can go much bigger without compromising air flow and turbo balance. Also the new 17t wheel looks like a perfect fit, I would assume going bigger would require modifying the turbo completely. I don't know, that's just what I was told. I wanted to go bigger, but EG told me that there was no need...

Haré romel

I don t know, i thinking spend money in aftermarket turbo is better. And that so...

TheWrench116

iTrader: (1)

seems like a few people are going to be getting the turbo upgrade from blouch. it will be interesting to compare notes and see what a different builder can do.

crxtype-r

i hear that, blouch is near me and you wrench . good peoples and very knowledgeable . been around for a long time. have to wait and see.

TheWrench116

iTrader: (1)

I was asking about other options instead of clipping the turbine wheel. maybe extrude honing the secondary exhaust passage and getting a slightly bigger internal gate for it so I don't loose any response. they said it only takes time and money. sounds like I might be a Ginny pig but I'm cool if it gets me the results I want!!!

KenB350z

I have a couple of after market turbos in mind, and don't mind spend $1500-$2000 on a turbo. The question is will it fit, do I waste 2grand on a turbo that isn't going to fit, or do I wait for someone to do it?!?

MrBlue

Yo Wrench!! I would like a copy of ur current Tune and the one U get in Jan; I cant make it out to PA for a tune. I am going to start ordering the needed upgraded parts to get at least 270 whp. Do U still have a Cat Installed? We don't have emissions testing in Mt so i plan on deleting the Cat which will allow better exhaust flow, cooler EGTs, and should see some HP gains. Would U still buy the RV-6 down pipe or have U come across a better idea? I need two open bungs; one for an AFR and the other for an EGT sensor. Any other changes would U make starting over? I already built my 3" cold air intake last year.

What R the parameters of the stock turbo (max PSI)? I am guessing the stock MAF is capable of handling all the boost (PSI) the turbo can generate. I know the older stock H22 MAF were limited to 11psi.

Any input will be appreciated as i plan or ordering parts SOON!!!!

MrBlue

I found the parameters of the stock turbo (17 psi max) and the MAF (26psi).

Will post dated dyno numbers. Similar numbers to TheWrench116.

Need to re-dyno once I find noise/phantom knock/etc.

TheWrench116

iTrader: (1)

when did the prelude have a Mass Air Flow sensor (MAF) I thought they only had a Manifold Absolute Pressure sensor (MAP)

2 very different sensors that measure air very differently.

also I wouldn't bother adjusting boost pressure yet that stupid cel keeps coming on...

TheWrench116

iTrader: (1)

just a heads up I did find a shop that will match rates for dyno rental and they have E-85 across the street. so if your in to that let me know and also give me enough time to do some homework on it so I'm not going in blind.

wouldnt let me attach the type of file but if you want to see my current cal for comparison purposes hit me up. its specific to my vehicle and elevation in colorado though.

Can you guys running FlashPros reflash stock ECUs with your calibrations? In other words is it locked to your specific ECU or can you do multiple flashes to multiple ECUs? Alternative to Hondata reflash and can be customized to specific setup I'm thinking. Not aware that Hondata does reflash/mail-order tunes for bigger injectors/turbo, etc.

bluecarbonfiber

need to have the option for multi keys to reflash multi ECUs here is a link to the dealer flashpro http://www.hondata.com/flashpro_dealer.htmlyou can share your calibrations though with anyone who has a flashpro.. the only thing ive noticed is the pre calibrations that hondata saved for it for the years 07-09 arent allowed to be used on the 2010-2012 models.. ive tried and it says they arent compatible even though its the same engine =(

flash pro is locked unless your a dealer.

and yes no code. but its not perfect not yet.
