Help me!! I am an excellent driver and my car is only trapping at 107 mph and pulling 13.1's. I paid to pull low twelves and plan on high 11's. I got a quote of around $3,000 for the same kit REnnTech needs $5,100 for. This being ECU flash and Pulley... adds 40-50 hp... Now I have to do the labor myself? is this a major deal to do?? Does the radiator need to go out?? Also anyone just done the Powerchip flash with no pulley?? How did that work out for under $1,000? I believe they charge..... I refuse to be beat by an Evo!!! Even if it was 95 degrees 13.1 is unacceptable. Yes I hooked up and had a .310 R/T. 109 octane... Lets keep that between us until we get this figured out...!!!++++++

 

Straight 109 octane? If so, then that is probably the problem.

 

The pulley adds boost so just a chip alone would not be as effective. Installing the Pulley/dampner is do-able at home but if you screw up the crank snout ...be prepared to pull your pants down and bend over at the dealer to replace the crank. Its not all that much to have a dealer install it.I think most will tell you the 109 isn't doing anything for you and in fact may be hurting you.

 

Irish,

Let me clear the air a little for you. This is a very simple decision.

1. A chip tune alone (with no aftermarket pulley) will not give you ANY noticable gain on the street or track.

2. If you ever mention "Speedtuning USA" like it's a reputable firm with a strong product for the E55, I'll rip one of your arms off and beat you with it (just kidding). Actually, they're ECU tunes are crap for the 55K motors. I know, I had one installed by Oliver when I was trying to go the cheap (inexpensive is a better word ) route like you are mentioning. Don't waste your money.

3. Get a kit from a reputable manufacturer (Renntech, Kleemann, or even Evosport) and be confident in your purchase. Don't do the install yourself. Pay to have it done right just to eliminate you being the reason for a mistake.

Hope this helps and good luck.

Regards,

Darren

 

Yeah man, Speedtuning are GREAT people and hopefully they have worked out the kinks, but LOTS of trouble with that flash. If you wanna be the guinea pig, Speedtuning sells a pulley and ECU kit for like a grand or something. Buyer use at own risk of course.

Don't forget what every modder keeps in the back of their mind. New crate E55 motor installed runs 44K, no *****.......so choose your mods and installer wisely.

Keep us posted.

 

Take your car to Dyno-Comp in Scottsdale. www.dynocomp.com Have them do a baseline dyno to make sure everything is OK, then the RENNtech stage 1 and after dyno. They can also provide you with a 100 octane software file for the track as some guys from the board have done.

 

I also recommend Dyno Comp. They are not cheap but do high quality work, getting it right from the start. A lot of people end up there after others mess up the car. Also they can program the ECU on site, rather than having it shipped around the country -- this is important if the dealer ever overwrites the program or if updated tuner software is available.

The summer gas here in Arizona sucks. But the 109 octane isn't what you need. Try filling up with 3/4 tank of 91 premium then top off with 1/4 tank of 100 octane race gas, the resulting mix gives you 93 octane. You won't be pulling timing with that; anything higher and you are just wasting dollars.

You can get 100 octane at the pump at the SE corner of 56th and Bell in N. Phoenix. There may be a station in the Chandler that has it too, maybe near the track ?

 

I would recomend you go to Speedworld on the other side of the Desert rather than the Firebird ice skating rink and watch your numbers improve. My best time at Firebird is 12.42 Speedworld 12.22. It is just less used and better prep'd in my opinion. You can join us Sunday the 15th if you would like. Day of fun. Check it out at www.scottsdaleexoticcarclub.com

irishspeed specifically stated his car hooked up. anyone that has raced at firebird knows that hooking up isn't possible with an e55 that's running the way it should. his 13.1 @ 107 is due to the recall, pure and simple. NOT track conditions, NOT gas, NOT anything else!!!

...been there, done that.

 

Oh I am sorry, I wasn't paying attention to what year his car was. It seems that those with the ECU reflash problems are on the '03-'04 models. My bad!

 

no apologies necessary as i wasn't directing my comments toward you...i was just making a general statement that all of the variables being discussed are beside the point. it's that damned recall that's the problem.

 

Make sure your IC pump isnt going out either.

 

I recently took my E55 to the strip for the first time, and could only manage a 13.03 @ 108.6 with a 60' of 2.01. I have no data prior to the recall, but i also am very upset with the cars performance and am going to look to dyno then chip. Do you guys think a good ecu tune by kleeman or renntech would give me my original power, or additional power on top of what i seem to have lost? Any insight would be appriciated.

 

Your 60' is part of the problem.What was the track elevation? What was the weather like,temp/humidity,baro? Theres more to going fast than just showing up and racing.

No,an ecu tune will get you nothing.

 

Have Powerchip on mine, great results.

 

He also said it was 95 degrees....Chiro how long has it been since your recall ???

 

while i agree that temps and summer gas will decrease performance (although not to the extent that this recall has), there are far too many verified cases to continue looking for any other excuse or explanation. it's time to accept the fact that this recall has affected some cars and try to find a solution.

btw, my car had the recall done in may.

 

This was my first time to the track, and my tires were below the wear bars (i have since replaced them). Elevation is roughly 500 ft, temp was 85. I was not expecting a hostile response, just looking for some helpful information. If an ecu tune would not give results, why would anyone buy one?

 

Sorry if thats the way it came across to you,by no means was it supposed to be hostile.I was just trying to give some insight like you asked for is all.I would suspect the weather was worse than you imagined and or the ic pump might be going bad.You could have other things wrong but Im betting it was the weather that day is all.Wait for a day with decent weather and put it on a dyno,get some pulls done and make sure you get an A/F reading printed out.You see adds for ecu tuning alone but the majority of people with 55's done get them,they just dont provide any substantial gains.You will see people get the pulleys and NO ecu tuning and have good results though.

Wait until the colder temps get here and then take it back to the track on a busy night when theres enough cars to keep the track sticky but the air is nice and cold.You'll see a difference then for sure.

 

Sorry, i had a fairly bad day yesterday so that might have been responsible for my response. I plan on getting it dynoed my next free weekend, and then trying to make it out to the track some cool night. If i take my car in to the dealer, can they specifically check the IC pump for failing?
