ok here is the set-up
89 honda crx
dohc zc swap
ihi thunderbird turbo
stock map
450cc inj.
255lph fuel pump (from xenocron)
i have a map from chris's bin dir.

i have replaced the fuel filter (just did today) and the injectors are working great but what my problem is when i hit boost whether 1psi or 6psi(what its set to) and i come to a stop the car will die,ill let it set for a minute or two it will start right back up. i have no codes even after it dies and starts back up. i dont know what it could be the bin i have is set-up for 440cc inj. but i have 450cc which a couple people have said should make no difference and its also set-up for a 2bar map which i have a stock map sensor maybe that could be the problem but im not sure. please help me in the right direction of what could be wrong.

You can't run a 2 bar map on a stock map sensor. That is your issue. Reburn with the stock map sensor option.

i have another chip with the stock map sensor on it and it does the same thing.so what could be my problem? the chips are from two diff. people the one i run right now is from chris and the other one i have is from john

mabe you are getting a 'gap' in your fuel supply. I would try driving around with a fuel pressure guage hooked up and stuck up onto the windshield. That way you can see if you are loosing enouph fuel pressure to kill the car.

I would also check around by sprying carb cleaner to see if you have any vacuum leaks. If your idle is abnormally high or if you have a wondering idle, this may be your problem...(you can also do this by blowing cigarette smoke under the hood around various vacuum lines, you can see it get pulled into the leak if there is one...)

no vacuum leaks that was one of the first things i checked. i have an adjustable fpr coming and i need to get another fuel press. gauge to check it. but i have checked just about everything else that i can think of. also the car will idle all day without a hiccup it only does it when i hit boost and then come to a stop and try to just take off normally.

Hmmmm...the only other thing that I can think of is to try a different chip and see if you just happened to get 2 with wierd problems....

i have 2 dif. maps from 2 diff. people and they both do the same thing. the car dies after boost with both maps

Whats your A/F's look like at idle and in boost?

sikcrx89

they are about 15-15.7 at idle and anywhere between 12-13 in boost
