Change your diff ratio to a 3.54 - if you have an auto with a 2.59 it's a completely different more fun car , effectively you *will* "up the torque"....... and shred tyres and get out of shape on the 1-2 and maybe even the 2-3 upshift , you wont be beaten from the stoplights by ricers or...
I don't think you can just disconnect the knock sensor as it will retard badly when the engine gets to 190+ degrees , I think you need to put a 4.7k 1/4watt resistor on the wire that goes to the KS and then ground that. It fools the ecu that the KS is still active but just wont retard any. I...
I have posted Coreldraw Drawings for the instrument panel and centre console for an 86
C4 Coupe with Auto shifter. These can be taken to any shop that does laser cutting (engraving type laser - not the high powered steel cutting ones) and they can cut these for you in a multitude of materials ...
Hiya , I have many laser cutters and engravers in my factory and am making a dash dress up kit for myself , in doing so I have removed the instrument panels and centre console cover so that we can match up all holes , legends etc. I did so cos my horn button wasnt working and needed access to...
I'm in the same boat C4-4 - my last vette was a C3 and I know plenty bout old school stuff - this computer stuff is a little confusing to me - Im getting an OBD1 cable to attach to my laptop and have downloaded some logging/diagnostic freeware for my C4 and hopefully will get a little more into...
Ta for the reassurance
I noticed something was amiss when one day the doors wouldnt open after I put the heater blower on , I really struggled to break the suction.
Worst of all , when the car landed here it had a 4 speed overdrive reverse and only one forward gear :)
I would just like to know if this is normal for an 86 L98
On open road the car runs at 80 degrees C on a cool day - not much more than 85 on a hot day
(178 - 185)
The fans come on at precisely 101c (215F) and go off at 91c (195) in stop and go or traffic
Car has no cat and none of the emissions...
Ive adjusted the Detent cable so I get full throttle. Im going on a nice 300km Muscle car run tommorrow - will see how it all pans out then.
Addendum
Car went well on the run , had it up close to 235kph and it seemed to have more steam to go faster , wasnt on a long strech of road so couldnt...
I just stuck it back to 6 degrees - I was 2 degrees out on the "seat of the pants" feel thing , 2 degrees advanced. I bought it with brand new tyres - 255/50/16's , off idle , it won't light the tyres. It will if I reve it 1000 or so on the brakes.
I just did a head gasket change and a full...
I know it's old school.. I'm waiting for an OBD1 cable to see where I am , at the moment its "seat of the pants" and I do realise that the timing map might be wrong as I advance ... Im just playing around right now as I'm not used to these modern newfangled puterised engines... :)
I just find...
Well , unleaded here in South Africa is 97 octane , thats all you can get .
I generally set my timing to where it starts pinging and then back off 2 degrees. That has been a quick and dirty way I have used quite often
I been advancing the vettes timing a bit more , hear no ping , but at a...
Hiya , thanks for the replies
Well , my mileage is quite good , I average at 16.5l/100km which is in line with my 96 Camaro and good for a V8 which is mostly driven "spiritedly" in town and heavyish traffic.
I didnt warm the car up - which is probably the issue - says to do so on the sticker on...
