ecotec swap (Page 41/98) wftb MAR 24, 10:53 PM picture of my new brake discs and the car on the road again : wftb MAR 27, 02:01 PM every winter i make improvements to my car .then i drive it and some of the improvements turn out to be a step backwards .this year it was my new air cleaner: turns out it just isnt big enough to flow enough air .the engine was running out of power at 5500 rpm .so i had to revert to the old filter and make up a rain shield to keep the water off it .the new filter had an open ended cone cover built in to it so a water shield was not needed .fake carbon fibre too so it looked nice .but it has a very small amount of filter area and was not up to the task .pcs of my new setup: i put some padding on the edges that does double duty to also funnel the water away from the filter .now the car pulls strong up to 7000 rpm again .much more fun . wftb APR 07, 11:56 PM did a bit of tuning on the car .after i changed some things on the PE and HO timing charts last summer i thought it ran pretty good but it seemed rich and my gas mileage dropped a bit .but i left it that way because i did not have time to mess with it .i came to realize that most of the changes to the timing were unnecasary because the water meth injection and the vortech FMU was doing the same thing as the changes i made in the PE table .other things i had done to the tune seemed to be causing my LTFT trim to be in the red at anything below 2000 rpm and the timing dropped drastically at anything over 10 % throttle opening .i realize now that the tune i borrowed was for an engine without water meth or an FMU .so i put the tune back to mostly stock and scans i have taken show a big improvement in LTFT , the timing stays up where it should be and there is less KR and my mileage is back up to 32 mpg town driving /40 mpg hwy .the motor is idling and running smoother now as well as feeling a lot stronger in the upper revs .some people would now say that since my tune is so close to stock then what do you need HP tuners for? so this is the changes i made to the tune and car with HP tuners: 1-injector constant changed to 0.13350 for the 32 lb injectors . 2-speedometer change to 23200 ppm to correct for 245/50/16 tires . 3-redline changed to 7000 rpm . 4-speed limiter raised to 150 mph . 5-VATS deactivated . 6-raised idle to 1000 rpm . not huge changes but all things that make the car better for me .HP tuners is not cheap (the MPVI pro package i have was 650.00) .but i think it has been well worth the moneyespecially for the diagnostic tools .i like driving with my laptop connected and seeing all the engine parameters as i drive along .i can also delete any thrown code with a stroke of the keyboard .i went on a little holiday this week to the monday practice round of the masters .had a great time .but now i come home to my fiero covered in snow and freezing temps .hope it all melts tomorrow .norm says my flush mounts are being shipped this week .it will be nice to drive at night again . Fosgatecavy98 APR 08, 03:48 PM What brakes did you put on it? I just got done with my Berreta Brakes all the way around wftb APR 11, 09:04 AM the kit i bought originally was from RCC .it came with 4 Lebaron rear rotors ,camaro front calipers ,cadilac rears with the parking brake built in ,and front aluminum hubs and custom mounting brackets .but the rotors fit too sloppy on the hubs so i sent the hubs back to get a ring made to make the discs fit better .the guy at RCC swore up and down they were the right size but they did not fit the discs he sent me .he never sent them back to me , inspite of numerous calls and emails .while i was waiting i had the discs cut off and ran the stock hubs that fit perfectly with the lebaron discs .the setup has evolved to include street dreams drop spindles and the new front discs i just put on .if i do another fiero i would just buy the caliper brackets from a supplier and source everything else out myself .i would stick with the 11" discs because i just cant see needing any more stopping power than i have now .the increase in unsprung weight is not worth it .i got back from Georgia tuesday night and got greeted by a snow storm and the fiero was covered in 6 inches of the white stuff .global warming , what a bunch of BS .

Damn, that's no slouch! Can't wait to ge me an ecotec! wftb APR 25, 06:11 PM thanks .it does seem noticeably faster than last year's version .the problems that are showing up though is my intake air temp is still too high during a full throttle run , not extreme about 40*C and my LTFT trim is in the red below 1500 rpm.my KR is way down to the point of almost non existant , that is the one major improvement so far . Fosgatecavy98 APR 26, 01:59 PM Good stuff, bump for ya.
