ShamelessTT Posted March 14, 2009 Share Posted March 14, 2009 Hi all, Today i fitted my Blitz IColor boost controller. Fitting was ok as i followed some guides off here for other controllers and the Blitz manuals. Anyway my Supra is STOCK (both cats still in) and is getting between 0.7-0.83 bar on full boost (which is correct from reading around). The boost is reporting fine from the boost controller. However!, the RPM is reading always well below what the actual RPM is on the dash. I have linked this to PIN 58 (B connector) of the ECU (IGF igniter, as read from posts on here) but its always quite a bit off. The speed reading is always 0, and i linked this to PIN 2 (A connector), which is whats the blitz manual and the ECU pin outs say, but no joy. Ive checked all the settings on the boost controller are correct for the RPM signal etc, and i cant see anything wrong. Dash still works fine. Question, i have tried to raise the boost to 0.9 on the boost controller just as a quick test but i can never get to this reading, which i assume is due to cats still being in?. Any suggestions?

Homer Posted March 14, 2009 Share Posted March 14, 2009 Can't help with the RPM issue, but regarding boost.. You should be able to get more than 0.9 bar with the cats in, but it's highly not recommended. They are a huge restriction, particularly the first one, so before you go more than stock boost, that one should be replaced. Do you have an FCD installed already?

ShamelessTT Posted March 14, 2009 Author Share Posted March 14, 2009 No i have the FCD ready to go in, but again it wires to the ECU....and im worried it might use speed signal again which im not getting a reading for. I checked the continuity so i know its wired ok. Cheers Quote Link to comment Share on other sites More sharing options...
patrikbrunt Posted March 15, 2009 Share Posted March 15, 2009 the FCD wires into the map sensor mate, no link to the speed sensor wire Quote Link to comment Share on other sites More sharing options...
ShamelessTT Posted March 15, 2009 Author Share Posted March 15, 2009 cheers, still at a loss why the signal is off for RPM and no Speed signal. Wonder if anyone can confirm the pins are correct ive used. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 15, 2009 Share Posted March 15, 2009 Pretty sure pin 2 on the A plug (single one) is the correct one. As you look at the ecu, it's the second top right pin. Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted March 16, 2009 Share Posted March 16, 2009 How far off are the Revs? Quote Link to comment Share on other sites More sharing options...
ShamelessTT Posted March 16, 2009 Author Share Posted March 16, 2009 Its about 200 off at idle (it says 380 ~ 420) and its seems to be off more at higher rev ranges. There are 3 settings on the Boost controller for th tacto, 3 cyclinder, 4 cyclinder , 6 cyclinder , and 3000rpm above or something. If i put it on 6 cylinder as it should be the idle reads about 110 the only way i can get it half close is with the 3000rpm one.

MrRalphMan Posted March 16, 2009 Share Posted March 16, 2009 Mine is out according to my SAFC at all revs, but as much as ~300RPM. As long as it's not miles out, I think that's fine as the speedo and Revo read high. Quote Link to comment Share on other sites More sharing options...
ShamelessTT Posted March 16, 2009 Author Share Posted March 16, 2009 Problem is its tons out, like 1000rpm ..........and im still getting 0 for speed signal It all seems to be wired correct Quote Link to comment Share on other sites More sharing options...
ShamelessTT Posted March 19, 2009 Author Share Posted March 19, 2009 Fixed now!!, i had been stupid and miss read the diagram for the connector blocks. It would appear by fluke i had tapped into something related to RPM but not the actual RPM signal. For forum reference, i can confirm its Pin 58 on block B (RPM) and Pin 2 on block A (Speed). Also for the blitz icolor i found that to get the speed reading perfect it had to be set on the following , 4 - Pulse reading and in MPH (Even tho my cars a JSpec i would of thought the ECU read in KPH but infact not) I installed my FCD today and all is working well, hitting the stock 0.8 bar constantly now, so cant wait to fit decats, plugs and fuel pump thats been gather dust in my garage.
