STIs run as rich as 8:1. That is really extreme.
Getting anything richer than 9:1 to light off is a trick, especially in the somewhat inefficient combustion chambers of the rotary.
10.5: is more than safe.
Misfires will show up as rich, even if they are because of a lean situation.

All that matters is power. Set up for a known rich range (just do the math) and then back out the fuel until you hit peak power. You are better off pulling timing to quell knock than to add fuel - up to a point (-10° to -12° off of factory timing).

 

Hey Lschiavo, what was your RPM at max HP?

Gee.. mine runs lean and then seems to level out around 14.

Maybe it's time to run an Emanage or CZ unit.

 

Around 5.7-6K

 

Ok guys, I dont have a scanner and the picture is hard to read. So I put it in paint and sketch the lines. Now you can see better how it looks. This is a very weird dyno sheet, but as I said before, we did 3 runs and all of them look very very similar, same trend.

Any opinions? Has anyone seen this weird phenomena of having such a drastic change in torque???

Thanks

Red line = Stock
Black line= with Greddy Turbo

P.S. The car feels incredibly powerful between 4K and 7K. It is so fun to drive

whats the chance of you posting that map of yours?
I just put my Hi-Flow back on yesterday and I would like to see what changes you made to your map...I'm using Jeffs right now and it helped tons but since I put the Hi-Flow back on I have the obvious backfiring and the power falls off a little in the higher RPMS
I'd appreciate it if you don't mind sharing...I'm going to the Dyno tomorrow with some other guys so it would be nice to be closer to be at what I want.

I think I may be having the same issues as you guys. I have a drastic difference in power at the low rpms 3-6k, but it feels almost stock if I go any higher than 6k. I'll have to make a dyno appointment this week. I wonder if Greddy changed the tuning. It doesn't seem like any of the earlier kits were having this problem.

But 200hp at the wheels still isn't that great. Not worth $3k. Hopefully that number will improve significantly on the other dyno. I will be very dissapointed if I only make 20hp more than stock for $3k.

 

PM'd you.
I'll post it up tonight after work. I've also got a side by side screenshot of the fuel changes that were made but I can't get it below 150KB so I can't post it. I'll try to compress it more and post also.
I don't mind sharing, but like I said earlier, every car is alittle different so use at your own discretion.

 

I'm sure the low numbers are due to the mustang dyno. The butt dyno tells me the car pulls strong. I didn't dyno before the turbo so I'll never know how much increase I got.

 

What dealership did you take it to for the compression check and how much did they charge you?

 

dont just look at the top number. look at the increase throughout the rpm range.

 

Yeah, some people don't get that. Area under the curve is what's important not just peak numbers. The shaded in areas are all the hp/tq I gained.

 

You have to realize that is a completely different type of dyno. A lot os stock RX8's dyno around the 150 whp on these cars, so that is still a 50 whp gain (+33%, which would be about 60 whp on a dynamomater dyno). When I first put the turbo on my car I had 4 psi across the board & a total of 40 whp gain, then I tuned it a bit to 6psi across the rev with 4 psi on the top end & 52 whp, now it is 7.5 psi, 6 psi on the top end. It will be inline with what Greddy says (60-65 whp). If he can get to 210 whp on a Mustang that is pretty good

 

Here's my tuned map and a side by side comparison of how much fuel was taken out (the blue cells are the ones that were changed).

 

I can feel it, My engine is about to blow up. It detonates in the street and goes rich on dyno. It "pinges" and I find the dyno sheet to be very unusual for what i've seen so far. This is horrible. I don't know if i am regreting putting the turbo on the car. Everytime I accelerate I think "this is it" i think it is gonna blow the rotors out of my hood. I am panicking LOL, some people tell me the pinging is due to fuel octane, some others tell me it is the spark plugs, some others tell me it is the emanage that's bad, and some others tell me the car is lean, some others tell me its rich. I dont know what to think.
LOL

 

Your dyno sheet AFR's show your running rich.

 

Dude, you're running WAY rich. Read all the comments here about tuning and your AFR.

Peace

Luis -

A. Stop the panic and stop driving it around trying to blow it up

B. Dont you have some mechanic and tuner types around you since you drive this

C. Get the plugs checked. If they are bad that could cause misfire which would show as rich on the dyno.

D. Get the map in your emanage checked. Either compare it against MazdaManiacs which is posted her or get Greddy to check it for you. If fact get on the phonewith Benny at greddy and let him know what is going on. Im sure he's read this but it would be beter to talk it out.

E. Take a deep breath.

F. Repeat E

G Run the highest octane you can get at your local petrol station. That will eliminate the possibilty that you are having octane related pre-ignition.

 

I had my car on a dynojet today.
Mainly to compare the numbers from last week, which were on a mustang dyno and the numbers were quite low. 194hp/ 164tq (might have been 3rd gear since it was tuning).

All the runs were done in 4th gear. The 1st 2 runs were scrapped since the techs couldn't get the rpm signal. My results from the dynojet... 218hp/ 180tq.
My AFR's were between 11.5 and 12.2 on the red run (not sure what happened on the blue run AFR's).

I didn't change anything from lastweek. I will gain alittle more hp when I get my boost controller in and holding 7psi throughout the RPMs (right now I'm at 6psi and drops down in high rpms).


Lschiavo, our dynojet graphs are the same at 5,500k rpms. (175hp/ 180tq). But after that yours falls. Your tunning too rich, check out my AFR's, between 11.5 and 12.2 .

218?!?

 

Very good improvement Adrian, keep it on!!

I will start tuning my car next week, I will try to load the mapping you posted earlier to see how it works. Yes, our car looked similar before you started tuning, so it is good since it shows me i have a long way to go.. Adrian if you have a newer and better emanage map let me know to try it. Thanks

 

The last map I posted is the most current. Make sure your engine doesn't knock.

OK, you got me.... 217.9
If your questioning why it's lower than greddy's 240whp, I don't know. Different dyno, different temp, maybe they dyno'd at 7psi.

 

I will use that one as base setupbut making it a little richer and working my way through it to get it to where i want it...
Thanks dude , very helpful
