I replaced my wide band and attempted tuning the car for meth injection. I was able to add a good deal more timing. Lot easier to set afr with a working sensor! I also tried the "No fuel trim at WOT" mod. Seems to work well. There is still much room for improvement I'm sure but here is a log I took earlier. This is using a 375 ml/min nozzle. Here's a link to some pics https://www.evolutionm.net/forums/09...8607-snow.html

I think I have the boost error correction set too fast. No boost spike at all and a little jagged. It pulls hard like never before. Now I need to find a supply for the meth rather than buying the premixed stuff for too much $.

Please feel free to voice your opinions.

 

looks not bad

 

Although i understand the adventurous factor of this idea, i've sat here for a week trying to think of why you decided to tune with meth on the stock output turbo.

Meth yes while boosting octane levels in the chamber which will allow you to add more timing and boost, doesn't have a benefit on this platform, heres why.

1. The turbo has been time and time over maxed out without fueling or cooling issues with simple bolt ons. Adding methanol to that mixture doesnt allow for much more power if any to be made due to the turbo being at its threshold. You can only make the lil guy spin so fast and push so much air,something we do on a daily basis without the addition of meth.

2. Yes methanol is a great cooling agent when its a mix with water. However, as stated earlier, we dont have a heat soak issue with our car, if the cheaper intercooler replacement option has been done (evo x coolers are 200$ roughly).

Ideally this setup should have been used if you moving to an fp green turbo and required the added fuel and cooling at that point. Additionally you run the risk of a foul out on meth, im hoping that youve taken the steps to make sure it cant happen (led light in your cockpit that turns on when the pump is on, and a low level indicator) and have planned to turn the system off and retune for winter, as the lines and or pump can and will freeze at low temps.

All the power to you on this project though, any data collected could be used later on for other applications, i just don't see the benefit.

 

Good luck with it. I'm not a fan of Meth. Kind of like drugs to me. Be careful that you need to monitor cylinder 1 the furthest one from nozzle. That will get the least amount of meth.

 

The benefit here is only on the added timing and possibly on the afr if I chose to run leaner (which I don't). I agree the turbo is maxed out. I can only get 91 octane as I don't much care for the husky 94. I am learning as I go, and I ususly prefer the road less traveled so I decided to give it a shot. Let me assure you that the extra 5-6 degree of timing I have added did not go unnoticed! I do have the leds you spoke of. In addition I have the output from the Safe Injection wired to cut boost if low flow is detected as I stated in the thread I linked to.
Yes, I do plan on the X turbo at some point.
And yes I have an URIC and both pipes.
The meth injection setup all cost me less than $500 so it was fairly cost efective.

 

What have people seen for power/torque using Evoscan? I have no reason to believe that this is at all accurate, but this is what it gave me after a few pulls this evening.

 

EVO Scan is not very accurate... You need to use VDR... Im still using the 5.71 version and its very accurate as i have compared it to my dyno charts at AMS on there dyno jet. Send me a log of your car on a 3rd gear pull on FLAT ground with only you in the car with your weight... If you have a passenger i will need to know there weight and i can give you a read out that will be VERY close to dyno jet #s.

PS. It wouldn't hurt to do a few pulls to send.

Id be very curious to see what my timing table is in corralation to yours. I would hazard to guess the meth tune your are running isnt running much more, which could be due to a number of factors. In 2006 i ran a snow performance meth kit on my Ion Redline and produced 294 Whp and 265 Torque on 18 psi. The major benefit at the time was timing as well, but the main reason was to cool the blades in the super charger. We knew that the car could produce more power with the meth, because the supercharger had more to give if cooled properly. Im not sure the same can be said about the meth.

Also im curious to know if you are running it pre turbo or post turbo.

If you could post a screeny of your timing tables ill ask my tuner tomorrow what mine looks like to compare.

Thanks.

 

Here is what VDR 5.71 says. I entered 300 lb because I figure my sub box and stuff is around 80 pounds. I gotta smooth that out some. Struggling with the MIVEC a bit!

 

Whoa turn that smoothing up to around 12-14....

 

Updated with a pull from this evening. Just the mivec has changed up top. Still can't get that dip out. Tried everything I can think of for mivec combination in that area.

 

where is your rev limiter set?

 

Limiter is at 6800. I never let it hit it though. Boost drops off far enough by then that I don't want to push it.

Along with the benefits of mivec, also comes the possibility to really hinder performance as well if not set properly.
