I have a leak tester that I made last week if you need to use it.

Just clamp it on, but you need a pressure source and a bike pump don't cut it volume wise.

I would suggest some basic mandatory parts as well as the basic short block, things like timing belt, upgraded oil pump, water pump, pulleys, KillerBee oil pickup, factory gasket set etc. The majority of time spent on a build is getting all the little parts together.

Ok good idea. Most of those parts I can get the next day from my vendor or dealer even as well. We did land on the upgraded oil pump but you mentioned the oil pickup that should also be part of our basic build. Thanks!

There was a topic retrac and I were pondering a while back and I want to ask.

On a target boost chart, if it is set up so that it's targets are linear throughout a throttle position and you use the boost controller to then vary the boost, is there a benefit to this?

basically 50%+ throttle was set at 19.81 for all rpm ranges and under 50% was set to a different number, the adjustment was then done by the boost controller. I tried this tune, it boosted like a raped ape and seemed to bring lag way down, however we didn't play with it long because for some reason the tune we jacked had some idle issues cause 10:1 afrs at idle and IAM's of 1 or 0 at times (16 bit). So have you ever set a boost chart up like this, and could you make it work like that at all?

^^ That was a canned tune from the guy with the same mods. You never tried to adapt similar changes to YOUR tune instead of the canned "base-map" one. Might have worked that way.

Part throttle boost tuning is an art. I wrote about this earlier in the thread here.

My question to you is why allow any more than spring pressure at part throttle? Set the targets to stock for part throttle ranges. If your running an after market boost solenoid then drop you WGDC tables about 30% from stocku numbers and start with that.

Some problems with some things you wrote. IAM at 0 or 1 with a 16 bit ECU? 16 bit range for the IAM is 0-16. If you were reading 10:1 at idle and had an IAM of 0 or 1 then you had some serious problems with the map. I'm trying to imagine how you even get a 10:1 at idle without changing front O2 sensor scaling while in closed loop. The car can make up to a 40% total change in fueling during closed loop operation. So I guess you could have forced it out of closed loop, had messed up MAF scaling, injector scaling, or some combination.


Nothing personal but ff your able to make mistakes that large I would avoid tuning your car for now until you ask more questions and get back to the fundamentals.

That's exactly what was done if I recall correctly, but it idled and ran smoother than it ever had before like that which was weird.

My feelings on the map dropping to IAM 1 was the wicked overdriving of the turbo by requesting those crazy targets down low which are undoubtedly way outside the efficiency range.

The idle issues are related to physical issues not tunes in my opinion. Running a car rich at idle will almost always smooth out rough spots.

The IAM dropped because you had high timing in the cells for that part throttle boost region. The turbo actually was spinning less since the thottle was part shut and I assume lower rpms; the only time this doesn't ring true is if the BPV is cracking open, then the turbo would over spin real fast. Blow dryer style!

There is no reason to run high boost at part throttle, but if you choose to you need to log load/rpm/boost/fbkc/iam figure out where the timing is getting pulled and pull it out yourself from the base timing tables first. Then you should review the advance timing tables to check for hot spots. Remember the stock tune was never designed for that kind of boost at part throttle. You will find some seriously advanced timing where your knocking. You will also see some very lean fuel trims perhaps as well.

Keep in mind I am speculating here since I don't know what you guys actually did.

Know the real problem? I was just a junk map with weird stuff going on all over. And of course we know that idle is mechanical on that car, but he's gotta get the kinks worked out.

I'm not really sure what your saying. He asked me as a favor to look at the tune quickly last year. The only thing I ever looked at on this car was his boost after he changed the solenoid... At the time he asked for 15psi and thats what he got. Since then I know he has made changes to the maps. I don't claim any responsibility for his tune...lol

Right, the change Rob is talking about was an opensource base map that was applied, not a tweaked version of his existing rom.

I see. Well you guys should come over some time and we can go over the tune. What better car to experiment on and learn with then Greeenys!

you say that like I care .

as paul said, it was a tune we found with my mods off romraider forum, and I looked at it, was was like, paul lets try it I wanna see what it's like.

Basically it was fun for 2 mins until the IAM's went to 1 on the first pull and the afr's sat around 12.7 at full boost. (personally like a lot richer) .

when I looked at the tune I was hoping for some better boost marks on throttle roll on, along with a bit of lag decrease, each I felt, but the problem was the IAM's and really messed up idle.

Ps, my idle issue is fine, as long as the temp is over 20 degrees, under that is when I have the CEL, plus, my cold idle is a bit strange.

In terms of boost, throttle, lag; When you put your foot 100% on the pedal the ECU only reads the pedal position and desired boost(for ur version, not all cars). This being said what you set in the ECU at part throttle will have NO effect since the ECU isn't even looking at the cells during WOT. The time it takes your foot to push the pedal from where ever to the floor is faster than any turbo will ever respond. If you found that you suddenly had better spool times then perhaps there is some thing in the tune beside what your looking at that needs to change to improve those times. My hunch is when you went to 0-1 IAM the severely reduced timing and rich condition aided the spool. I could explain why but we can do that another day.

Unsure on wear.. haven't heard any "horrible" noises yet. lol
You should contact Blackstone Labs for an oil analysis kit. Draw a sample on your next oil change to see what the wear is like. It'll cost you about $22.50 plus some postage to send the sample to them. They will email and snail mail the results to you.

Have you thought about a "Core Exchange" program to go along with it? It could help keep costs down too.
