You have a mail in flash, you cant expect it to be perfect, but it should generate smoother power than that.

does the power curve generated by this dyno reflect how the car accelerates in 4th gear? That a/f trace looks nasty eveywhere & the power drop-outs suggest timing being yanked. Once again, in 4th gear, does you car pull smooth or like you see in that dyno sheet?

Did quirt(owner) do the dyno'ing? Did he give you any price break since you were the 1st evo he put on his dyno?

have them re-dyno your car in 3rd.

Be staight with quirt & tell him how you feel. He's a decent guy. They build strong subies, so i wouldnt expect him to dick anyone around, regardless of car type.

Doesnt his dyno mount to the hubs or does it use rollers & you just drive up on it?

Good luck

 

Oceanside is in CA & that is the highest non racegas octane u can get in CA, AZ, NM, UT, & parts of WA

as far as the threadstarter goes, u could get the S-AFC but only if u know how to use it. u wopuld be better off having Works flatten out your AFR to the mid 11:1 area & only Shell Vpower 91 allows you to get the most timing out 91octane. your other option would be to run a water/meth kit but i hear they're not allowed to use on road race courses for safety reasons...

 

yea, I think bill did the dyno and quirt probably would have known better. I'm going to re-dyno it and see if they can help me out.

 

Then they would have a really bad memory. They dynoed a bunch of EVOS at RIM.

 

yea , bill told me he had never dynoed an evo before. But, that could have been just him. I ask politely if I can re-dyno it.

 

update! heres the new dyno graph in 3rd gear pull. BIG difference but the horspower loss is too soon I believe. let me know what you guys think. Expert advice would be nice. A/f ratio's remain the same in every gear?

 

think I should send the ECU back to works for a retune?

 

Just a question. Do you have an upgraded fuel pump? I did not see one in your mod list.

 

no, no upgraded fuel pump and with the power at the flywheel I'm making I think I should get one.

 

all that bumpiness seems to be consistent near the high end in both gears. would that suggest a need of a fuel pump? The a/f ratios near the high end seem to be on the lean side.

 

I honestly cannot tell much from this graph. All I know is that your torque still falls from peak but not as much as before and your power curve has peaks and valleys in the top end.

As I said before, forget about this shop and go get a custom tune at a different shop that uses a dynojet so you can compare your results to others. Dynojets are the most widely used dynos and they measure at the wheels. The one you are using measures at the flywheel.

I would also adivse you to get a fuel pump. It adds a measure of safety to your engine.

 

Yes, you should get one. Most tuners almost require them on their flashes. I believe you had the works flash right? They may have flashed you for the pump. Check with them.

 

well I checked with works and no, they did not flash for the fuel pump. but they said they would analyse my dyno graphs, mods etc... and tell them what type of dyno was used, they would give me a suggestion on what to do. I myself believe I need a fuel pump upgrade because I checked my plugs with 4k miles on them and they seem to be really white in the middle and the electrode is fine with no carbon build up whatsoever. I also checked the outer rim of the plugs which seem to be slightly burned and black. this signifies super hot conditions and lean. This also verifies the fact that my car is running at 190 degrees farahnheit avg. for oil temps when it used to be running at below 180.

 

what would happen if I run race gas or 100oct. unleaded from VIP in this situation? hmm.....

 

Second graph looks like better gas
