so i installed my gruppe-m intake today and went out for a quick "check" if everything´s alright.i went to my gf house to show here the intake, which is about 12 km from my home.everything went great no CEL or other problems.
after i arrived at my gf home i just let the car sit for about 5 min. or so and than went off for the way home. after a quick sprint to 140km/h i thought "since i have to brake anyways i´ll let the car roll out"....and so i did. i got into neutral and the car rolled.all of the sudden ( at about 700 rpm) the car stalled . all lights went on (CEL, check oil,...). i let the car roll out till it came to a total stop and turned the key off and then on again and the engine started the first time without any problems!!!
i had to drive another 15 km or so home,but the car just ran nice.

any ideas what this could have been?????

i disconected the battery during the installation and didn´t even get a CEL after i started the car the first time.
or should i have had the throttel thing done before driving??

 

sounds like the MAF had an overflow. I've had that happen to me with all kinds of intakes (popcharger, blitz sus). From what I recall reading it's that the ecu/maf is throwing a fit cause too much air is coming in and it doesn't know what to do, so it stalls.

 

just talked with my dad about that "problem" and he told me that his ZX7R does the same at high speed (roll outs). i guess since it´s a ram air system now the air get´s much better inside the intake and causes an overflow such as you stated.

 

Try relearn ecu.
