Stalls when coming down to a stop and only does it occasionally. Usually my rpms go to roughly 500 or so when I come to a stop. Works great if I just engine break down to about 1k though. Anybody else have this problem? Im sure that when I get it tuned the problem will be fixed, just couldnt figure out why its doing it with the base map.

In my experience, it's b/c it's running lean. When you get a wideband on it, set the idle AFR to no leaner than 15.0:1 and give the throttle a blip. It should come back down without a dip before it settles to the target idle rpm.

Also, when you first start the car in open-loop and watch the AFR, it'll probably be pretty lean (16.5:1 or higher). That was my first clue to pinpointing the problem.

Stock injectors?

yeah that happends to my 89 prelude also... it is clogged pcv valves... and yes a tune up fixes it.. but u hav to make sure they clean/replace those

RC 370 injectors. PCV was just checked when i had the engine pulled apart. Im guessing its running lean as well, but its almost like when it cuts fuel for engine braking it just cuts it back on too late.

it's gotta be running quite lean. Sucks that your basemap isn't better

Check the AF ratio and then
get it Tizzzuned

Thats what I was thinking....Im a bit worried about driving it around now(well....atleast past closed loop mode).

it's because you have a basemap.

Thats weird...

your point? Basemaps are suppose to be pretty close to right. Kinda like my stock ecu can handle basic bolt ons...sure you can get more power by tuning, but its close enough that its safe to drive around on. Hell even with my stock injectors and stock ecu it didnt stall out like this...thus if the base map is for 370s, then I should have no problems.

Well I wouldn't drive around too long on on basemap, it main purpose is to get your car started and get you to the tuner. When are you getting tuned anyways? I'm sure that will correct the problem and it seems your running lean at Idle. Other say you could be running rich, which is also a possibility. Sometimes with basemaps you get the wrong map, misinformation, trust me it happens alot.

You sure its not from running to rich?

Thats what i was thinkin

TeamSTEALTH GSR

i doubt hes running lean with those injectors at low rpm... i think its very rich..

check your spark plugs, if u dont have a A/F meter

LBR92DA-T

im pretty sure its rich.. i had the same problem but no hondata.. i got tuned all throughout my powerband... except idle...

I'll be going to Jim at motorvations in Birmingham, Alabama. Ive got a friend with the Kpro($1000 system for the RSX) and with his basemap he was running pretty rich(around 12.5:1). On the other hand, the base map could be way off. Im mainly waiting on exhaust(header/cat/exhaust) before i get it tuned. Should be here soon though.

I'd be interested in hearing about what you observe.
