What you think of my tune?

Ok well this is the tune that the MS has on it atm, I just fetched it. Btw, by no means should anyone just copy this and go thrashing, it will kill your engine :). Im just posting this up to get some opinions on whether this tune is reasonable, just so that I can rule it out as a culprit in my engine blowing. I intend on using this tune (very close to it) when I get the ZE running again (hopefully with the 10:1 pistons still, if not my spare DE internals depending on where the damage is).

I can provide the MSQ file by email to anyone who wants to have a closer look.

Need anything else to get the big picture, just ask :).

would prefer to see a datalog'd run instead.

your ve map doesnt tell much when there are so many variations of setups that can be run.
I 100% agree with King, but aside from that in the ignition one, the 2700x25kpa cell seems out of place, and the transition from your idle region to normal seems very sharp. Mostly they should be smooth, 3d views would help show that pretty well.

What is your AFR/Lambda target curve like? That is a good one to look at on a screen and go yes/no. Then you just change the "ve" to make the AFR match the target as best you can.

The car doesn't run so datalogging is impossible :).

Idle is a bit funny because my idle speed motor is stuffed and he said he fixed my idle. I thought that was impossible seeing as the idle speed motor is screwed but when I got the car back, idle was on 700rpm so obviously he played around until he got the idle right.

So I cant show much else without the car running ay?

Have you ever datalogged? Also made a AFR target table?

shoot I run a datalog almost everytime I drive the car, you can alwase go back and see whats going on. To hard to keep moniter things while driving, atleast for me.. bad at multi tasking...
I dont know much about tuneing MS, Ive used the analzyer to dial in alot of areas... and so far everything has been running pretty much dead on






Just noticed when screen capturing those, my most recent tune's are setup with afr bins I got from strealth (not the ones I pictured) That explains somethings.....

A) Why is it not running?
B) Tell me you saved the tune from before this guy got hold of it?
C) Why did someone get hold of your car?
D) Not sure what else to ask, but, WHY is it not running after someone has been tuning it??

That's all I guess.

A: Most likely head gasket, by the amount of smoking that was coming out of the PCV/ breather, probably cracked the head.
B: Of course :).
C: Dyno tuner
D: It was running fine for about 1 hour, I noticed loss of power, all of a sudden smoke started pouring into the cabin and down the street. Quite dramatic. Started missing the whole way home, going to check spark plugs for water now (ive been away for a few days on holiday). When I got it back from the tuner, it drove and idled beautifully except for loss of power and larger then usual exhaust leak from rear exhaust manifold gasket, and smoke coming out of the camcase breather. Also my starter motor died, the car got cooked basically. Didnt overheat (water temp) on the dyno.\

King I cant datalog everytime I take it for a drive because I drive my car everyday and that would just be tiresome. My car isnt just a toy, it is transport. I didnt get to go home with the car tuned as I had some errands to run, it blew on the way home.

This weekend im putting the KLDE back in, then cracking open the ZE to get a good look at the damage. If it isnt too bad, rebuild for the ZE. Like you say King, these engines are cheap to find. I just hope the head on the ZE isnt completely fucked, that would be the only thing that would shit me.

Hey thats why im here to rule the tune out as the problem. The car overheated last time (blocked radiator, but didnt overheat on the street) when I was on that dyno. It is in a very small air tight(sound tight) room. I dont think my little jap engine likes the enclosed space.

Just got off the phone to my mates boss(mechanic), he reckons from my description compression seals. Which is a good thing. The engine was low on compression when I got it 2 years ago. I would have to look at my post where I had it up, but it was mostly 175 with one cylinder on 168 or something. 1 year of thrashing NA, 1 year of boosting, then a big dyno session could of just ended it. The tuner also said that with the spark table I had in there before, the car was pinging its head off.
Never said you have to everytime. You could at anytime for just a few min. I only do it when I know im going to thrash on it, If im driving through the city stop and go for an hr.. I dont even take the laptop with me.
Did you run one at anytime before all this?


What is exaclty wrong with the motor? doesnt turn over? doesnt run? knocking? where does it smoke from? leaking oil? leaking anything? Compression test? coolant system pressure test?..
If you starter is fucked, push start it and make a vid.. wanna see the smokin bandit..;)
I say rule out your engine being blown first.
Well I push started it and drove to my mates workshop. It wasnt smoking THAT bad, well not as bad as the original day that it happened. There was smoke coming out of the dipstick, compression rings gone 100%. Not burning coolant at all, 100% oil from the rings. The car is sitting at the shop now and tomorrow night me and my mate are going to pull the ZE out and start putting the old KLDE in. This summer in about 2-3 months im going to build up the ZE, luckily the head is ok so will be reusing it when the forged internal ZE goes in:).

I have datalogged before but not with this tune.

Also I might be getting a free 1983 toyota corolla wagon as well as a runabout for just in case.

Only thing that im a bit worried about is with the KLDE my tune will be near useless on it right?? Meaning I will have to start from scratch again? I suppose it might make an ok basemap..?

At least I can rule out the tune as the culprit for the blown engine. I had been driving around on that basemap thrashing the tits off it on an already dieing engine for too long. I am just so happy the head is ok. To me that is the most important part of a ZE as they arent exactly cheap to come by anymore.

My compression results from 2-23-07
1. 165
2. 175
3. 160
4. 175
5. 175
6. 175

Funnily enough the engine blew cylinder 1 and 3 :).
I intend on rebuilding this engine and having the piston seize itself to the head or something as bad probably isnt going to make it any cheaper :). That compression test was from 2 years ago almost.
Man the car doesnt even start, the starter was fucked and I only just got my hands on another starter today at 4pm after the engine was already pulled out by this morning. I just got back after all day at work, 3 hours at evening class of uni, to then drive with a trailer to my house to grab the DE and take it to my mates workshop.

Smoke coming out the breather, the dipstick oil pissing through cylinder 1 and 3 (my mate told me this and he hadn't seen my compression test results from back then before he told me), smoke coming out of the PCV valve. How much more obvious can it be of fucked rings or at least a fucked engine somewhere. I dont care how fucked the engine is, it was already dieing, and I need a car to drive. I didnt have time to wait around for a starter motor to turn up or get mine fixed, I need a car this week.

Im not getting shitty incase it came across like that, but sometimes I can tell every post I write doesn't get read. No ability to crank = no compression test. I cant let the car take up a hoist at a workshop so I can find out exactly how low the numbers are. The engine is dead, that is all I needed to know. In 2 days of getting back to my car, engine is out and new one is getting dropped in tomorrow.

Also, I might be getting a free/case of beer Toyota Corona 1984 rwd manual wagon tomorrow with no rego as a runabout. Will be nice to have a backup car.

I read your posts, but must have missed the starter issue.

The DE can make 400whp anyway, so don't stress much ;-) Just up the boost for the lower compression and use the car.

Sorry if I sounded snappy :)

Everyone else says "yer that spare engine will drive you around until you get the ZE engine rebuilt" but not you :p:tup:

If I get this second car, and the compression test for the DE with 200000kms on it comes back reasonable, then yes, up the boost will ensue.
Sidenote - King those AFR targets are setup for the AEM wideband voltages...

Turk - Hope you make better numbers on the new motor whilst your blown one is getting built.
