JTbo's project (360GL B200K 1988)

It is corrected graph. My fuel map is not yet quite finished, it goes bit lean at higher rpm, that is why there is so much zigzag as lamda correction is not keeping up too well

Perhaps next week I will have all set so I can get K-cam installed, in two weeks for sure. Could be that next week I put those wires bit better and some cleaning must be done. I do have now few pics, but they are bit scary, lol. All wiring is just thrown in there, some relays hanging from their wires etc. When I had this little problem that engine did not run properly I took almost everything apart and then installed back for quick tests.

Perhaps that whistling sound will disappear too when I get all properly back together again.

Hard to tell from the tape, but is the whistling not a belt slipping?

I would say that's the air filter whistling from somewhere,

Power map looks impressive. Interesting to see the HP/torque differences.

It comes from throttle body as you see there is two large holes, those are there for fumes from crankcase ventilation system circulation. I have blocked those so no air is sucked trough them, that is why they work as a whistle, grrrr. So I think that I need to open the block and make circulation back to work, but before that I need to clean flametrap

That is at least my guess.

I edited my post where those curves are, so easy to compare. It was not stock in first curve either, but only few mods, exhaust, intake and flywheel.

Presumably if it's whistling, you just haven't got them blocked off fully?

cheers

There is gasket without holes installed and some gasket glue also, it is just those holes that are like a pipe.

I added some photos, today I managed to tidy wiring a bit, some wires are way too long, but it is very annoying to make them shorter, I need to think what I will do for them.

Now coolant temperature is shown properly, but some odd thing happened. As I was driving home from work I did around 40kph in 3rd gear, for some reason it goes wayyy too rich, over 146% richer than normally, it does that few times, but it is sorted with quick tap to throttle.

I need to look what did cause that, perhaps it is bad earth with lambda as lambda did show bit lean all time there too. Good that I had my laptop with me and it was logging too

Tomorrow is the day when my car enters to next level of performance (K-Cam installation)

My biggest worry is that they do something wrong in garage or they try to repair car that won't start and they have forgot to turn MS switch position ON.
Many things can go wrong, but let's hope best

Good luck.

Make sure they replace the timing belt with new, high quality, preferably original Volvo timing belt (only costs about 9 pounds, under 15 euros) I would retension the timing belt after you get the car back and cooled down, because they stretch a tiny bit when first fitted.

turn engine to No 1 TDC, and then undo the rubber cover that sits on the timing belt casing. Undo the nut a couple of turns to let the tensioner spring tension the belt. Then do up tightly.

New timing belt and almost everything that is under that belt cover is the plan, also new waterpump.

Need to check that belt then, thanks from the tip

I checked now my datalog and it was 200% richer mixture that it should have been, some reason lambda did show too lean there, must be bad earth with that lambda sensor.

30 minutes adjusting/driving done:

thats impressive

where does the dip in torque at ~4250 rpm come from? does the map still need a bit of work near there?

Post by **jtbo** » 03 May 2005 05:09 pm

I'm not sure where it comes, but fuel map needs lot of work, now I just made quick fix to rich and little adjusting around worst spots.

One thing I need to fix is that distributor cap, there is lot of black burning marks in one spot, crater I would say. New part already bought and some new spark plugs too.

It takes very little damage for a dizzy to cause a misfire. Get that K cam in

Can't imagine where it came from...

cheers
