Water/methanol Injection

[GUN-808]

I take that back LOL
tonights readings have put the AquaMist to a clear leader.. its the business !!

although its added another $100+ on the bill :( haha

and heres a cool chart with the players and their cost vs features etc

I had some more dyno time over the weekend, had some hiccups with my spark booster and was loading the car too hard according to some, but when I hooked up the water meth 375ml jet the car picked up over 35rwhp no other tuning. I also zero'd out all of the lambda multipliers and IAT multipliers for spark and even double checked my logs I took on the dyno. The car added no additional timing. Yes these results would have exaggerated because I was loading the car really hard on the runs (10km/sec) but there were no additional changes. I didn't lean it off or anything. Just cooler IATs on the back to back runs. There was no time cooling down between hooking the meth up either as it is only one plug in the engine bay and its on. But it went 499rwkw and pretty happy. Once I get the sparkmax and my tune sorted will do some more testing and keep you posted. Dave is actually helping me get the Sparkmax sorted. But I think with a larger plug gap there will be decent gains, that aswell as leaning it off a heap as it is still quite rich. .80 lambda

Well most of that went over my head, but it is great to hear some testing. I think the only thing stopping me from giving it a crack is the apparent silence from most of the tuners on this forum. They don't seem to be jumping on the bandwagon. That worries me?

So the Sparkmax thingy is basically a high amp voltage booster/regulator then?

What make of Sparkmax did you buy? (jms,kenne bell)

Have to be happy with 5 Hungy at the wheels! How much boost was that at Captain?

I think what puts some tuners off it is it opens up potentially. If you are tuning the car for more power using the Watermeth, it means less fuel and more timing usually. If you have a customer who doesnt take care of the car then you can imagine what will happen if the watermeth fails.... Seen this first hand actually on my cousins car. He had his water meth on a switch( Which I dont recommend) So basically we were travelling to powercruise. Had the big tune in on the xcal, forgot to turn water meth on, melted a piston. That is why I set mine up with a wiring harness, so if you want to disconnect it, physically have to get out of the car and do so and vice versa, so when I was using the xcal It would trigger my brain to make sure I change the tune in the xcal. The Sparkmax is the JMS/Herrod setup, is a voltage booster and increases output to the coils, very nice unit, bolts in actually, nice little bracket, takes 15mins to install. According to Herrod my issue is tune related and I have to disable Repetitive spark, unfortunately with HP tuners I dont have access to this table so I'm waiting for support to add it for me. Once that is done I will go and finish the tune. Im led to believe that with that sparkmax and leaning the fuel off to .83-.85 there is another 30rwkw left in the setup, maybe more if I can get the boost to stay flat. At the moment using the eboost it makes 25psi and falls to 20. I was planning on running an RPM correction to the Eboost to keep the boost at 25psi (or as close as possible) but it used the signal coming into the sparkmax. Once I disconnected it to troublshoot the missfire I could no longer run the RPM based correction.

Actually which one of you is running the AEM setup? I think I recal dave talking about on the phone the other day. did you get it sorted? sounded like a good unit. alot flasher than my snow stage 2

[norrs]

The reason I'm interested is more about intake temps than being able to run a leaner tune. I live in the tropics running a Sydney tune. I suspect it could make a big difference in darwin in the wet season.

[45T-XR]

I know it helps here mate, It gets pretty humid here In Gladstone too. I would go for it

[MattyP]

I'm in Sydney and I'm wanting it for temps as well

I won't add anymore spark on my e85 tune. Maybe a touch more on my 98 but I'd want to remove a bit of fuel

I don't have my snow kit fitted yet as I had made the brackets and everything was ready to go onto my ba turbo then we bought the F6X so I stopped at that point and will get around to fitting it one day...

I wrote the ba turbo off so it's definitely not going on it now!

norrs,

If you can mate I would get your car checked on a dyno and have the operator (or yourself) listen for knock and check the afr's.

I had my ba turbo tuned by Elite in Brisbane with the car making 330rwkw. When I got to Townsville the car felt strong still when driving around town but once the day heated up and if I was still out and about it felt lazy and didn't come on strong.

Anyway... I took it to the local drags and the car only ran a flat 113mph, with 330rwkw it should have run at least 118mph!

Took it to my local mechanic and the car dynoed 307rwkw (both dyno dynamics) but because the tuner in Brisbane (Tim, who is excellent btw) set my afr's at 12.5 (injectors were maxed) the afr's up in Townsville were even leaner (13.0:1 on initial boost) and the temp, humidity etc are totally different to down south my guess was that quick squirts were ok but a quarter mile was to much for the tune and as a result power was robbed during the run...
