Lag ass.

norMecha · 11-14-2006, 03:17 PM

So whenever i start my car up for work in the morning i wait a couple mins then drive.. but ive noticed theres a lag when its first started up in not just one gear but first thru 3. It acts as if im not giving it any gas and then the power comes back at a higher rpm but in the 1 to 3000 rpm range it just lags. is this just do to it still warming up. thanks.

JWT ECU?

norMecha · 11-14-2006, 05:21 PM

yea its a JWT ECU

eric96ser · 11-14-2006, 05:23 PM

Common problem, and there's nothing you can do about it.

norMecha · 11-14-2006, 05:50 PM

ahh sh!t. why is it that way anyhow..does it get worse..?

When I had my JWT ECU I also had the common hesitation problem.

It really never got worse. It just stayed the same.

The ECU retards timing alot when you go WOT at low RPM, so no, it wont get worse. Nothings really broken, its just really conservative timing to prevent detonation.

Why not just wait a few min before you start driving? till it gets to normal temp.

norMecha · 11-14-2006, 06:34 PM

awesome thanks guys.. any other quarks about the ecu...does my car need to go on a dyno to run "right" or be configured better? or by having the jwt and ve motor as is good enough? what are some off the bat things i should know , me being used to a de motor. anything i should be careful of etc?

so its a tempeture thing not a programing issue?

eric96ser · 11-14-2006, 06:57 PM

Yes, 148 deg is the magic number. Under that, and you have the issue described. Above that, and it goes away.

norMecha · 11-14-2006, 07:07 PM

thanks. my questions above ^ still apply as well.

eric96ser · 11-14-2006, 07:11 PM

No amount of dyno time will fix the problem. I've had it for 3 years.

danilo20 · 11-14-2006, 07:15 PM

never had that problem with my JWT ECu, and i bought it from a guy who had the same problem with the same computer. sooo.............. Dunno

norMecha · 11-14-2006, 07:51 PM

ahh well...fugit. what happens if you need to rip it though and its bogging, by flooring it screw something up other than the normal wear and tear from ripping it.

civicdragon · 11-15-2006, 01:05 AM

so if you give it a little gas it still does this?.. i had this prob on my turbo jwt and it cleared up a lot when i changed some of the vacuum hoses

i have a safc 2 and my car is tuned a little lean and when its cold it does the same thing as you guys are talking about, just puttin something out there

i'd have to agree. but heck, they warm up pretty quick anyway. usually within a couple of blocks for me

ha usually warmed up with liquor and booze and pass out at the scene of theyre mess.

no when i do give a lil more gas its cool...i think its the ecu though. or maybe the timing.
