Default Begi S kit fully warmed up.

This is a begi S kit. Keep in mind the dyno was done at the end of a very hard and very long day. 300 mile drive to get all hooked up + all day of driving crazy to tune it.

Barely ran 18 degrees at 5k, anything over that would ping and the ecu would retard anyways.

This was with a 99 10th edition
I was running adaptronic ecu, 800cc injectors, 2554 turbo, stock exhaust from the cat back. Regular downpipe, not the seperated gasses one, and no intercooler as the s kit does not come with one. Air fuel ratios were 11.5-12, 6 psi wastegate, 93 octane gas.

I suspect the VICs was not working at that time either.

How much boost? 5?

You need to open up the breathing on that bad boy

SAE smoothing at 5 and very jagged, looks like its detonating above 5k rpm. It also looks very poorly tuned, that little turbo should make for a very smoothly shaped torque curve, and that you do not have.

Are you running cold plugs? what octane?

You should get on a FMIC asap too. Check out my threads to see how I set mine up. Its kinda a pain compared to an NA.

Did you log the pull?

It doesn't look healthy.

800cc and 140whp? Are you planning to dump this turbo soon?

I don't think its his turbo holding him back yet. he should easily be able to hit 200whp with an exhaust and fmic on that setup.

Most likely 240 if he goes over 10psi.

I suppose. I was just thinking 800cc is overkill. Could have gone with less for less ...unless he had bigger plans.

Couldn't you hit 140hp on a NA 1.8 with exhaust, intake, and an aftermarket ECU? Something ain't right.

Time to download and post up some pictures of the tune for us to look at.

It is intercoolerless... but still... ick.

Next time you dyno, make sure to unlock your fixed timing to 10* after setting the initial timing...

in fact, next time you drive do this.

Past 4K you are making LESS torque than a stock 10AE. That hurts to look at. Post the tune, there is something horribly horribly wrong.

I like to check my vertical revs against my horizontal revs, just to make sure the engine is balanced properly.

You = needs more tune

6 psi, 5th gear (6 speed tranny). The tunning was done by Travis from Boundary Engineering.

The big dip at 5k is because of detonation, he first ran it at 20 degrees and it was detonating out the **** so it was lowered at 18 degrees.

Ignition map looks usable (hard to read). Have you verified your timing with a timing light?

Your torque curve should be shaped something like this:

Just uploaded a new pic of the timing map. Something like the graph above is what i was expecting too. No we could not verify the timing with a timing light.

Also heres a vid of the run.

Make a test map with 10* timing everywhere (don't drive it that way!), fire it up, and put a timing light on that thing. Make sure the marks line up. For a '99, you should see two marks with the light, one will be on 10 BTDC, the other on 0 or "T".

I'll lock the timing at 10 degrees and run that instead After all its only 1 button
