i read about the throttle delay on a tsx but i dont think its like what i have
normally i feel some delay also and kinda used to it already

but when shifting from 1st at redline to second gear im having a massive delay it feels like over a second long
like i have time to look around with that WTF look on my face and count to one mississippi (whatever the spelling is) and then it goes.
i checked all i could. everything seems to be in place there are zero codes for any systems
and i tightened the throttle cable as soon as i found out this is actually a halfassed drive by wire system.(another wtf honda lol)


i know some people just replace the app sensor and sometimes it works someitmes doesnt its not a cheap part to replace
is there any way to confirm that its the app sensor faulty for sure or is it something to do with the actual TB servo system faulty?
what do i need to check before swapping parts blindly?

btw when people replace the app sensor and it fixes the problem what exatly is the fault with the app sensor can i test for it?

I too notice the huge delay between gears. Mine is there on every gear. VERY annoying. I heard if you keep the throttle at least 5% open it won't lag so bad.

fuzzysig

checked the throttle and app with the scanner
app shows 0% closed 100% with gas pedal down
TB shows 18% closed and I think 76% with gas pedal down
it shows 2 different voltages for app but I haven't really looked into what it should be in the manual yet

is that normal to have such difference in the values between the app and TB?

I tried moving the gas slowly and didn't notice any fluctuation on the graph either
tb graph seems to follow app graph consistently without any spikes

is there really no way to fix this without hondata?

fuzzysig

can i offset the app sensor or something?

why does it happen anyone have an explanation?

can i use the APP pedal from 2008 tsx since it is built in the gas pedal?

11.5 years, and have never experienced any of this..Like, NEVER on my TSX

You could always try a Buddy Club e-throttle booster. It works on DBW. on most Honda models. Tried it on a test RSX Type-S. Did well

fuzzysig

ill try to make a video some day.
its really is like over a second delay from first to second gear. and shorter from then on
does throttle body servo fail at all on these?
the tb is clean and when i move the app the throttle opens smoothly
can it be anything else not related to tb or app sensor?
at first i thought it was from engine rock but i fixed that
all mounts and front suspension bushings are new and proper rotaiton with car leveled...
spark plugs look good still
good o2 sensors and low mileae cat from a 60k tsx
i never checked the ecu though. maybe something burned

it lterally just hangs for a full second
i go through first gear
press clutch at redline
shift to second as the rpms drop
release the clutch and step on gas
and theres nothing while im flooring the gas
and then a second later it jsut picks up like i feel the throttle body opening
from second to third and so on its a very small delay its there but not as dramaic as first to second.

Perhaps I don't attempt to shift as aggressively, knowing that revving in 1st gear to redline for the car does nothing. You're outside of the optimal torqueband of the rpm range to warrant that kind of shifting, anyway, which is why this is 2.4 litre, and not some 1.8 B-series rpm monster.

The computers of most 2005+ Honda ECU systems integrate a small amount of "rev hang" for emissions purposes, and to save the valves. You can't just drive these like a normal throttle cabled system from your B-series without some sort of aftermarket control. This is why I recommended the buddy cub e-throttle booster, that changes the % reading of the accelerator position sensor. I've never seen a replaced APP sensor or pedal assembly improve anything, without accompanying engine management.

fuzzysig

sad dog face...
i see. lol yea i do miss the b series. it was very effortless especially type-r motor. should have never sold it. made 200whp 136tq on a stock usdm spec motor with boltons after rebuild and balance.
made more power than my stupid gsr build that i spent x2 amount of money lol

i probably just gonna sell this tsx and get a 2008 i think its a much better starting point to do any kind of modification since the motor and ecu are already there with all the improvements

I think you're wasting your time going from 06' to 08'. There isn't a "problem" in the first place. As an owner of both, there WAS NO DIFFERENCE in hardware/software, ECU or performance. Even the '09s had a different intake manifold composition & design, but only changed the torque numbers a bit. EVERYTHING ELSE WAS COMPLETELY THE SAME.

As for your "thumping" you're hearing, its more than likely the rear endlinks and bushings, which tend to wear out MUCH SOONER than the suspension. The suspension in these are one of the more robust systems available, and TSX in particular is the last of the double-wishbone suspension systems created. This chassis was used in more racing series as winners than the RSX Type S and DC5 combined.


I think you're just going to keep going through cars until you go back to the B-series, where us old heads belong. You're expecting too much from these stock systems that are running DBW and CAN-BUS integrated systems.

Just stating my observations from your last several threads you started in attempting to modify the K-series in stock chassis.. You expect too much to be able to modify from the jump.

fuzzysig

lol its funny because i almost posted this tsx for trade for a 4 door integra just cant replace integra it was my first car... alot of memories

isnt the 06 and up has better internals? stronger rotating assembly and bigger valves etc?
and i wont have to buy the ecu in order to get the ktuner isnt the 08 plug and play for the ktuner?
plus 08 also has more interior features liek disabling that stupid auto lock for the doors
this is my first k series so it was more of a test run to kinda poke around the car and see whats what now i got a better idea of what im looking for

i also found another way to reflash them
theres a guy in russia that just did a turbo legend kb1 with a reflashed ecu and a piggyback
he shared with me all the tools that he used which cost about same as buying a kpro or hondata. they re not RTP but allow to reflash any 2004 and up honda/acura and its worth a try
he has a database of basemaps for pretty much every year model including RL kb1 he said he can tune any j series the only limit is the stock map sensor so no boost without a piggyback


but yea theres a 100% chance of me owning a b series car in the near future.. i just cant replace the feel. all this electronic assist **** is pissing me off lol

My comments are in red.

fuzzysig

I mean I m not going back to only obd1 I'm learning about these systems now its good to stay up to date but the integra will be the car I keep just because...
I'm assuming you use hondata then? I haven't used either so I don't know how they are yet.

the Russian guy is more for the RL since there are no other options and he seems to be doing a lot of j series tunes with those tools successfully using tactrix and pcmflash/bitedit. which I understand is nowhere near as easy as hondata or ktuner but I like doing things manually anyway

btw how do you get into the programming lol I have no luck on 2004 tsx to change the door lock settings unless the 2004 doesn't have them I tried few yutube videos but no luck

Service manual. Best book around.

Sorry for the thread jack, but this part is very interesting. I had no idea I could enable auto lock on my 06, or any of the features you just listed for that matter. Could all this information be found in the owners manual by chance? And are you referring to the auto lock that happens when you unlock the doors but do not open them, or an auto lock feature that locks the doors once I start to drive away?

fuzzysig

should be both features.
unfortunately 2004 don't have the options as far as I can tell it started in 2006 the cluster I belive is also updated to show mpg and some other info
he 2004 just shows trip outside temp and brightness

The auto lock happens when you unlock the doors but don't open them. This is found in the OEM service manual, although not much detail. You have to sort of "play" with the settings. No different than resetting the oil % once you've changed the oil.
They do not lock themselves as you drive away.

hungrygreen_gsr

The part in bold I knew. I was just a little confused and started to get hopeful lol. I'm sure with a bit of googling I can find out how to reset and change functions. Just never knew we had the ability to do so. Thanks

just replace the APP sensor. it notoriously goes bad. odd throttle response is a typical symptom.

before i replaced mine, i had a code, but it wasnt flashing an engine light. mechanic thought i needed a new clutch and it was "my bad shifting". after he changed the clutch, he went to clear my ecu, i could see him scratching his head, he probably saw the codes then...

i checked the codes myself and i ended up replacing the APP myself and concluded i replaced my clutch about 50k miles too early. oh well.
