dawkins20 Posted January 28, 2008 Share Posted January 28, 2008 Guys, is this a problem with 08 model 5EATs as well? Just wondering b/c in theory the newer tranny shifts quicker, which could prevent this. Any first hand knowledge? Link to comment Share on other sites More sharing options...
fishbone Posted January 28, 2008 Share Posted January 28, 2008 I happens to my car too. It does not happen from a dead stop when accelerating at WOT. It only happens when I am at a slow roll before punching it. If I am rolling AND punch it AND the transmission drops down to 1st gear, I will hit the fuel cut every single time. I have now learned to just hit the + button on my steering wheel if I punch it from a roll. +1 I'm having the same annoying issue. The revs go all the way up to 7000 and it's a crapshoot. 80% of the time the car won't say anything and once or twice it will hit the fuel cut-off at about 7100. Someone said you do it enough and the engine will start retarding the timing? Oh? How many times would this have to happen? I've hit the rev limiter about 4 times since I've gone Stage 4 back in August. Would disconnecting the battery resume normal timing? I think what happens is, the TCU doesn't react fast enough, it seems like the increased power throws the engine in high revs and the tranny is not quick enough to shift. And God knows my transmission shifts nice and crisp, as it should, knock on wood. Link to comment Share on other sites More sharing options...
ArcTec34 Posted January 28, 2008 Author Share Posted January 28, 2008 i dont think you should worry about the ecu pulling timings.... i know mine was specifically only when it dropped from a higher gear back down to first and then during hard acceleration the 1-2 shift would be screwed up, and christian's beta map fixed it.. id reccomend giving it a try, seems like you're in the same boat Link to comment Share on other sites More sharing options...
fishbone Posted January 28, 2008 Share Posted January 28, 2008 That's a base map, right? Meaning, you have to reflash it the same way you reflashed it when you first went Stage 1? I've only hit my rev limiter when I punched it from a roll so the car downshifted to 1st. I have yet to have this issue while just taking off in 1st.

mcsquish Posted March 19, 2008 Share Posted March 19, 2008 So I'm wondering if or how many 05 eat (with a V1 AP) are having this issue? I'm to the point that I can make this happen at will. If I'm going to do any spirited driving I have to manualmatic. but I guess that's not all bad.......but getting a little annoying....... Link to comment Share on other sites More sharing options...

HNRB4LGT Posted March 20, 2008 Share Posted March 20, 2008 oh crap, i was thinking of getting an AP too. I hope nobody has that problem with the 05 5eat. For the last time, my car is not a Camry Link to comment Share on other sites More sharing options...
ArcTec34 Posted March 20, 2008 Author Share Posted March 20, 2008 some have, not all. im glad i bought the AP, its a very fixable problem Link to comment Share on other sites More sharing options...
ncretter Posted March 20, 2008 Share Posted March 20, 2008 It has happened to me a couple of times too--only under hard acceleration, and I think only when it gets into the redline in 1st. I assumed it was fuel cutoff/safety measure. (I have 05 5eat stage 1 93 octane) Also, occasionally my engine will dip down too low in revs before it has warmed up; it almost starts lugging (this is a bit more common than the 4000 rpm thing, but still pretty rare).

I had no issues really, only when it was extremely cold, car was cold and i was running a Cobb stg 1 map. never happened on my stg 2 etune maps. Wiggle wiggle wiggle wiggle wiggle yeah!!!

I have a 05 EAT and I'm not saying that someone shouldn't get one, the difference is surprising!! Just going to stage 1 was impressive. If you were to get a AP V2 the issue sounds like it is resolved, but since I went with a V1 AP I may just have to live with it, switch to a V2, or go stade 2 sooner than I want. But if you're looking at getting one, DO IT!! Link to comment Share on other sites More sharing options...

I bet your "extremely cold" is a bit colder than what we get around here........ is for your Phase I Part Out. Link to comment Share on other sites More sharing options...

jvento Posted March 21, 2008 Share Posted March 21, 2008 Yea mine even runs a little low but. Man I only have a gpmoto air-intake and a perrin tmic with no-tune thank god yet. Link to comment Share on other sites More sharing options...
cleaver Posted March 21, 2008 Share Posted March 21, 2008 I'm running Stage 1 on a V2 on a 2005 5EAT, and the Beta software from Christian at Cobb solved the issue. Email him about it. Link to comment Share on other sites More sharing options...
mcsquish Posted March 25, 2008 Share Posted March 25, 2008 Christian saves the day again! I can't get it to hit the fuel cutoff. It also shifts before it gets into the red line. THANKS!! Link to comment Share on other sites More sharing options...

sschmelcke Posted April 6, 2008 Share Posted April 6, 2008 i think im having this issue. it happened once at stage 1 i was turning left to get on a highway ramp and it felt like the car just shut off. i went to stage 2 yesterday and was turning right when the light turned green, got on it a little too much and the car wasnt happy with that.

fishbone Posted April 16, 2008 Share Posted April 16, 2008 I think I'll wait until the "official" one comes out, especially since I haven't hit this problem since I first posted about it, knock on wood as to not tempt fate. Link to comment Share on other sites More sharing options...
