Evo 9 blown...any ideas why
sorry no reflash was needed. Would of been a waste of money at the time. I had plans for later on down the road with the EMS. Just gonna happen alot sooner than expected. Now I have a reason to build up the engine. The car isnt my daily driver and have time to do it right now.
Ya tell me about it. Im not happy about that. I had my doubts on a few things. I should of done my research before i let him touch it and done it right. Ive always tuned all my other cars via AFC and never steeped into any stand alone systems so I let him do it cause I've seen a couple of the cars he did before without problems but none of the others were EVO's.
Well, I guess we see how, by melting pistons.
Bummer. Sorry to hear/see your misfortune. Once it's back together, take it to somebody that actually knows what they are doing.

I see that you are in chino so the closest shop to you would be tuning tech, you can contact alfred over there. Personaly I take my car down to Reese Tuning in San Diego, its worth the drive and they have extensive knowledge in tuning evo's with either AEM or flash
First off I dont appreciate that comment nor was it warrented. The only reason I let him tune the car is cause he is just about the only guy I know that has delt with stand alones and he has done good work in the past for myself and others. He has tuned a low 11 sec Honda street car with a N20/propane shot that has been running strong with a stock block for a year and a half without problems. If you had read any of my other posts on this topic I have already stated that I had made a mistake letting him tune it and that I had a feeling we needed a wideband but he had insisted that we didnt need one cause he was just going to modify the base map a little bit so that it wouldnt lean out on me. The car was running great for 3k miles without any problems.
Also would anyone know how much you can over bore the 4G63 block? Im looking into a new block but would like to use my old one if I can. There is a gouge in the side of the no 4 CYL if you look at the pics. I have yet to measure it out yet thou. It looks like maybe about a 1mm gouge or so.
You can always take your block in to the machine shop and figure out by how much you can bore up to and still have thick enough cylinder walls to make good power.
Now for autotune, you kinda need one for the ems to accurately autotune. Not everyone is aware of that. They see autotune and assume that the ems will get an accurate measurement of the fuel with a narrowband.
The same way people used to tune without a wideband, dorkstick. They'd bring it to the point of knock and back things up a little. There are people out there who still tune without a wideband.

Thank you for a little back up on this issue. Your point on the autotune is what happened. My tuner said that the auto should do the job without problem. Looks like the wrong idea on this issue thou. He was looking at the norrowband on the EMS while tuning and tring to get the car to run off that measurement.
Yes you can overbore a 4g63 block. By how much you'd have to bore it though I couldn't tell you just based off what I'm seeing and you're estimates. You'd have to take the block in and you're desired pistons in to be measured and have the block bored accurately. This will be the same whether you want to keep it 2.0 or if you want to go 2.3.

With a wideband, it actually can get you driving. Mind you, it won't really be all that good for WOT runs, but it will get you to the point of actually being able to drive on the highway and around town.
That being said, with autotune, you still have to calibrate it off of your wideband. You can tell it your desired AFR, and the EMS will run it at what it thinks it's supposed to be at. You have to log a few runs and tell it what the wideband is seeing, and then it will adjust itself. It isn't exactly automatic at first.
Also bear in mind that autotune is something that entry level standalones are now getting. Before, it was a feature on much higher end ems's.

We did a few pulls on the car with the laptop to watch what it was doing and adjusted the maps to what he had seen off the narrowband I guess. I was driving while he was on the laptop so I didnt see exactly what he was doing. CYL 1,2,3 sparkplugs looked good no evidence of leaning out. On no4 however the electrode was completly gone. pics coming in a few mins.
Hey I would highly recommend Road Race Engineering to build your motor. They built mine and are the best EVO shop on the west coast. Scot Grey from Road Race has a very good reputation but I have personally never worked with him. Reese Tuning is a excellent option for tuning. I had a great experience with them.
I have worked with TT, I didnt have a good experience with them.
Check out socalevo.net Road Race and TT are both vendors on that site

Sorry cant get pics to turn out good enough to post.
