To all that have the Gtech RR: is there a difinitive way to setup the Gtech to read the RPMs accurately. <br>I have tried varoius calibration settings/methods and cannot get accurate tracking of the RPMs. There is a firmware update, but it is not supported and you cant revert the update. Has anyone used this firmware?<br>I havent ventured into alternate electrical configurations but before I do, could anyone make a/some recommendations (other than Gtech tech support).<br>

Re: R and Gtech setup (martynunya)

I haven't even used my Gtech since I did the RR firmware update over a year ago. In Pro Comp form it was tricky but I did find I was eventually able to hold the RPMs steady in the R and use the standard calibration procedure. I should hope the same procedure is used for the RR. Once we return to cool weather I might have to try this with the RR.

Sorry for the dely,<br>The problems I am having are in the 06. I havent had the chance to swap it into the wagon.

Re: (martynunya)

Just tried Firmware ver 4.1.1 and still no luck.<p>Anyone running either of these firmware versions and getting good RPMs on the 05 and earlier cars? For those who are getting good RPMs what firmware are you running?<p>Pat

Re: (Pat S)

I have an '05 and tried everything too. I am currently running firmware version 4.1.1. I've tried about every version on my car, and wasn't able to calibrate the RPM's on any version.<p>On the current version, I thought I had it. The RPM's appear to match while low, but as soon as I go over 2K the needle jumps all over the place.<p>I called GTECH support. The guy told me the issue is that the GTECH uses the modulations in electrical system (caused by the spark plug firing) to read the RPM's. The problem with our cars is that our electronics do a good job of cleaning the 'dirty' electric and makes it cleaner - which is actually better for most electronics. Unfortunately it makes it harder to read.<p>It also appears that each car is different. Some people have no problems getting a RPM signal, and someone else with the same Year/Model car and GTECH firmware may never get it going. I think I'm the latter.<p>The guy told me to hook my GTECH up directly to the battery and that should work, and if it didn't I could also try hooking it up to the alternator. These systems were outside the electronics that would be cleaning the electric. I was phyched...tried the battery and it did not work. I looked at the alternator and couldn't easily figure out where and how to hook it up. The combination of that and all the other let downs caused me to give up before attempting the alternator.<p>I would be interested in knowing how others who had stubborn problems were able to get it going.

Re: (martynunya)

I don't know about the voltages at the alternator. I just used my volt meter to make sure I had the right wires connected to the correct terminals on the battery (to make sure the polarities were correct since I cut off the cigarette lighter adapter). I didn't even bother checking the voltages off the alternator since I basically took one lok at it and decided to give up.

Re: (Pat S)

Here is a thread with some useful information...<p><A HREF="http://forums.swedespeed.com/zerothread?id=51582" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=51582</A><p>for those who don't to dig... <p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>"R" Kelly</b> »</i></TD></TR><TR><TD CLASS="quote">-- IMPORTANT DISCLAIMER --<p>The R has a noisy battery line (or very quiet depending who you ask), some people have hard time getting it to work correct with the R. Also, the shift lights don't always light in time for 1-2 shift, cuz well, revs happen too fast.<p>Now, I had no problem doing the quick set up and mine worked fine for months. Then, I tried doing advanced calibration plugging in weight of car, etc, and then it didn't want to calibrate so easy. Had to cycle through about 30 different settings for it to work again. <p>Someone else had this issue, gave up and sold theirs before they solved the advanced settings issue. <p>So, my advice is, if it works after you do the 2K and 4K RPM quick set up, STOP. If you read the article, it is really accurate out of the box, not really any more accurate after doing advanced calibration. </TD></TR></TABLE>

I did both calibrations, and with the advanced, was within 7 hp of the dyno. I would like to check the accuracy of the torque figures.

Pat: the rpms still dont work. They track to 2500 and then go to hell. The HP is spot on, but torque is OTL. I will give it a shot in the wagon tonight.

Re: R and Gtech setup (martynunya)

I had problems in the past getting RPSs to calibrate. Tried all the standard stuff - hardwiring to the battery, and cycling through all the 30 settings. I did get it close on setting 6 or 16, but it would flutter all over the place at high RPMs.<p>Today I wired it directly to the jumper post in the engine bay, and the negative wire to ground. It worked like a charm and I didn't even have to cycle through all the 30 settings. I just had to rev to 4000 rpms and hit set, then 2000 rpms, and it was done. Works like a charm.<p>I was very frustrated with this in the past. Hopefully this will solve the problem for others. <p>-Bill
