Possibly the worst tune I've seen.

So here's the back story, I'll try to keep it quick. A friend just built his evo, top to bottom, with the goal of 900+whp. No stone was left unturned.
Head: CBRE & Tomei 280's Block: 2.0 turbo tuff and Billet Trans: Built, shimmed, syncroed and 4.11 T-case: built and reinforced fuel system: double pumper 340's (maybe 430's? Can't remember) and 2200CC high Z Injectors Turbo: T/S 6466 Ect Ect Ect You get the picture. He takes it to get tuned at a local shop and the results are HORRIBLE!! It can't idle right, barely starts, can't rev past 7K without popping and falling on its face and runs rich everywhere. I took a screen shot of their Timing map because i didn't want to laugh or be scared by myself. Here's the before: https://www.evolutionm.net/forums/at...ine=1414170589 And after we started fixing things: https://www.evolutionm.net/forums/at...ine=1414170589 We've still got a ways to go before it's as it should be, but at least he can now make power to redline. |
Well it's true that too low timing can really cause issues as well! :)

What kind of load is it pulling? Jw....sd?
|
can you overlay the load cells we are looking at? it looks much leaner and clean.
can you show us the afr's |

i wouldn't say its the worst tune. At least you have a map to start with to make changes. Looks like the car is responding to the increased timing well. Do you plan on trying another tuner or self tuning?

that timing map looks like ****, looks pretty half assed and lazy hopefully this wasnt Atlantic Motorsports because Ive seen similar from those guys

I have seen bro tune's worse than that you got lucky :)

well I was just making an assumption about the Shop considering what the timing map looked like. Not trying to throw anyone under the bus. Its just kind of a shame when you can look at a timing map and go "bing bing thats who did it!"

I'll share some of the artwork I've pulled from Cali evo's over the past year.
