So a customer drops his car off for an AEM tune

[DG]

12:1 - 11:1 - 12:1 in the space of 300 RPM? What does that fuel map look like?

The base ECU timing was never set. At AEM 15 degrees the actual timing on the engine is 5. That isn't knowing 3S tuning, that is not knowing AEM EMS tuning. This is one of the first things you do.

Sadly, there is no shortage of soi disant "t00n3rz" out there that really have no idea what they are doing.

That's one of the big reasons why I'm so keen on owners learning to tune themselves - they have a vested interest in getting it right.

Ok, so I started fresh.
Funny, the old map was setup so that the max raw number on the fuel table was 65. So even adding or subtracting 1 is a large percentage.

Setup basics and a basic conservative timing map still probably 5 degrees back. And on the rich side.

One outing with a few pulls. Yeah, she fees stronger. Still breaks up real bad when it hits 12-14psi. He has NGK copper 7's supposed to be gapped to 28 but I will pull and check, and a kennebell boostaspark. May remove that and see how it runs.

This was a first shot in the dark and set up rich for safety, missed it a bit as it's running 10.1 in boost. But that's easily fixed. Cruised a while and got cruise and accel/decel pretty good.

So even running 10.1 AFR (LOL) as compared to the 11.5-11.9 it was running, same boost, it picked up 50hp and 79 ft lbs tq.

Today was fix it day.

Lower plenum had 3 stripped holes, so replaced with a good clean used lower plenum and all 3 new OEM gaskets.

Pulled spark plugs to replace with a new set, to find oil on the top side of most of them, spark plug gaskets leaking. So all new OEM valve cover gaskets and spark plug gaskets. AFTER I cleaned off all the orange RTV off of everything.

Replaced a stripped T bolt clamp.

Need to figure a fix for the front turbo, the filter is mounted right to it and it smashes the vacuum hose for the wastegate, totally clamping it shut. No Bueno.

Tomorrow I need to hotwire the fuel pump. Currently it has sorta a hotwire to it but it's single strand house wire. Then going to bypass the Kenne Belle boostaspark for now as it also is wired in with house wiring.

More tuning and pulls after that is all sorted.

this car sounds like a mess

[Street_Chally73]

Wow, that sounds like some quality work was done to it before you picked it up to fix it all up...

I need to contact you soon about doing a transaxle overhaul along with some other things.

Today was more fix it before real tuning happens.

Front turbo wastegate vacuum nipple/hose was being 100% clamped shut by the mounted to turbo filter. And the WG arm was not clamping the WG shut.

So I shimmed the WG so it would keep the WG closed and find the WG itself is bent/crushed (not the rod, the valve section) So when I tested the WGs with compressed air to ensure activation and travel, it would go half way then jamb open, would not self return.

So, I was able to use my press to get it straight. Shimmed it. and slight reposition to keep the vac nipple from being pinched closed by the filter. It's all good now.

On to the fuel pump hotwire. Since I noticed house wire was used for the hotwire kit and the stock resistor relay was not bypassed I needed to correct it.

Bypassed the relay. On to the fuel sender plug to....WHAT? The house wire run to "hotwire" the pump was scotch locked to the fuel pump power wire. And not cut in, The stock wire was still intact, the house wire was just spliced in with it.

So new Ninja Performance hot wire kit installed.

Tomorrow will be tuning time.

Oh geez.

Sure hope this isn't a so called reputable shop or one of our vendors that did this work. Little bit questionable to say the least.

Great job though Chris.. Nice to see someone take pride in there work the way you do man.

Stand up work, as always. Can't wait to see the end result!
