bad mileage

[zwiersjuh]

Hey guys,

i'm running a 98 glanza with the following mods:

Manifold
downpipe
2'5" exhaust
hks actuator
Fmic
blitz sus filter
aem tru boost set on .85 bar

the problem is i only do 280-320 kilometers with a full tank.. last time i drove 200 kilometers wit a speed of 100kmhon highway with no boosting at all , and then i had 1:12 . My old glanza did with same mods and lots of boosting 1:14 and with granny driving 1:17..

Also in low revs it haves absolute no power, a 1 litre suzuki alto from 1988 is faster low in the revs..

what could this be? It haves nou fault codes, lambda is good, changed the plugs, checked the timing, swapped the ecu for a other stock one enz enz..

who can help me???

Cheers Erwin

simple start de waagen niet

i would say change/clean o2 senser and ecu temp senser and test de map senser all off these will alter feul flow check if a injecter isnt stuck open to

do u have rrfpr ??? pressure might be to high

thats what i would check first anyways

Already switched the temp sensor, and o2 sensor is good. I don't think it's one injector because all the plugs are greasy..

i see so mayby u have a injecter stuck open ?????

you can check this by putting a round bar on the injecter and put ur ear on the other end to listen to them pulsing

did u check the map senser ?????
