that is definitely the case with the blocks and not hitting most of them. However, thats the point of block tuning, to leave the guessing game out of it. Either way, the final result is what matters....

As i always say, tuning is a science, its the theory part that determines how and when you get to the numbers you want

 

great numbers man!!!

 

I have lean spool on. It sometimes gets close to 12.5:1 during spool but I rarely if ever see knock.

Aside from the posted maps I have the wastegate duty cycle modified for the #65 pill and the Check Engine Light knock mod. Thats it.

For the record the #65 pill is the stock pill filled with solder and drilled out with a #65 drill bit. Its alot like a DSM free mod! I still have the pill near the BCS to fight random midrange boost spikes during lapping days.

I'm sure I could get more out of both tunes but I prefer to feel comfortable with beating the car in any condition imaginable.

 

nice #'s

 

With how well the stock ecu is built (w/knock sensor) you can get away with block tuning the timing map, but it is far from ideal. Block tuning the fuel map as you have it makes no sense as you are assuming for example that you are consuming the same amount of fuel at low rpm low load and high rpm high load.

The numbers are nice, but the tune can still use work.

 

I usually see block tuning done horizontally, not vertical... so basically at 7500 rpm you will have say 10.0, 7000 9.6, 6500 9.4 and so on....

Its hard to argue with numbers though, but i dont doubt they'd be better with more detailed tuning, but if it works for you and you are happy, i really can only make suggestions

 

The second mivec map that he is using is MINE. I posted it in the Mivec thread. He slightly modified it and used it. I have no problem with that. It is NOT a TTP map.

Here is the link to the map

Make a log of a third gear pull from 2500rpm. Then use map tracer to see what cells were actually used. Those values wil be very close to one another. Probably withing two tenths of a point. Don't beleive me, look at the factory fuel map for an EVO9 in cells 260 and 280. They don't vary buy much at all. There are some values that are way off but you'll never hit those cells. I don't have time to dick with two tenths because odds are lean spool with adjust those values anyway. I acutally made peak spool richer than stock to keep the AFR flatter and safer.

I will agree that it could be dialed in a little tighter but I don't think I would see a significant return.

With boost/load changing as RPMs climb. Its a combination of the two. If you compare it to the stock map you'll see that anything above 4k rpm in the 260-280 load is the same AFR. The block tune works. My map is a tad richer where lean spool kicks in and because mivec is more aggressive.

The bottom line is you will rarely see a load higher than 140 at an RPM lower than 2500 so that portion of the map is not used. Your car should hit about the same load cells every time you go WOT so we are only talking about 10-12 cells. The map looks overly blocked but most of the cells will not be used.

As for the partial throttle boost and AFR adjustments my settings are right on par with the stock map it just looks overly blocked.

The timing map is blocked more than stock. But if you compare it to stock you'll see my race gas map has 11* more timing at peak torque and 12* more timing at redline than the stock map. I've tried staircasing the timing and didn't see the returns. Again the car is going to hit nearly the same timing load cells at WOT. If the map is blocked my partial throttle cells will be much more tame than if I duplicated the mitsu theme. Not only that but my tame cells are still a tad more aggressive than stock. So its safe and it works.

I know people are against block tuning but truth is it works.

 

i didnt say it was TTP's map, i said it looks like the map they use... and it does. Apparently it must work .... i use JohnBradleys Mivec map, so basically the same concept just a bit more aggressive.
Im not against anything ... if it works, use it. Getting to where you want your numbers is all that matters. How you get there is up to you. Its not like you dont seem to know what you are doing or talking about

 

Looks good Jeff. Post up some logs in the ECUflash forum?

 

^^ Thanks. I just want to make it clear the the stock maps are just as blocked in the load areas that are truely used that's all.

I'm happy with the car the way it is. The dyno really shows the power that race gas can support. I'm not sure what you guys pay but around here 110 is available at the pump for $5/gallon. Premium is $3/Gallon. When I mix up a batch of 103 octane the total cost is $4/gallon. Pretty cheap price to pay for safe 24/7 power.

Lastly a BIG thanks goes out to John Bradley and NJ1266. These guys spend an arseload of time testing, logging, and testing again so the rest of us don't have too!

 

Not trying to be a hater, but something is definitely wrong with that dyno graph which makes me question the peak power produced. The horsepower and torque curves should always cross at the 5250 rpm mark, but they seem to be crossing around 4500rpm on the graph posted, suggesting a mathematical error in the power calculations.

 

good numbers...

 

Using graph with the same scale for both this would be true. If you look at this sheet you will see that the graphs are independent. Power is marked on one side and Torque is marked on the other using a different more suitable scale. I prefer this over the typical mustang dyno print outs.

I'm trying to find a drag strip for next weekend so I can get a 1/4 time. This is truely the only way to measure the cars performance.

Here is a dyno from a friend's CRX. B20 block with B16 head - carburated - with a 100 shot (this time same scale for both).

 

+1 for JB.... he could damn well be one of the best Evo Tuners in the country..... and worst part is, its not recognized enough.
